"We looked everywhere. There wasn't a single tail plate for a Rotilian Reptool in the entire ravine!" Ace was beyond frustrated and she was especially unhappy about having to come back after failing to find what they needed.

"Sorry Rev dude."

Revvit, who had decided to remain above Ty's left tread so that he could avoid too much attention, was quick to reassure them both. "It is OK, I appreciate your efforts in trying to locate this part."

"But what are we going to do without it?" asked Skya.

"Couldn't you patch the one he has?" Dozer suggested. It may have come out sounding gruff, but he was genuinely worried for the little Tool.

"This isn't just some external plating we're talking about," Waldo answered. "A Rotilian's tail is a highly functional and delic- "

"So, no then." Interrupted Dozer.

Waldo looked at Dozer, deadpanned. "No."

"I have had some thoughts as to what other options were available, should this circumstance arise." Said Revvit. "If a replacement plate cannot be found then…"

"We'll just have to build one!" finished Ty with increasing excitement.

"Precisely." Revvit confirmed.

"We still need to find the right metal to make it from." Said Waldo. "If you want to keep full use of your tail like before it can't be made from any old scrap metal."

"It's too bad you can't recycle your old plate dude."

"Ton Ton you're a genius!" Ty exclaimed. "It's already exactly what we need…"

"We simply need to remake it into a whole piece." Revvit finished, looking at Ace and Skya.

"Like when Skya and me made the battering ram by melting down scrap metal in the lava." Ace realised aloud.

Revvit nodded. "Yes. Using the technique that you both came up with we can re-forge the old plate back into its original form."

"Then what are we waiting for? Let's go to the lava pits." Said Dozer impatiently.

Waldo and Click Clack wandered off to go and get the parts that they would need while at the lava pits, calling Ton Ton over so that they could put everything in his bed. Once that was done everyone headed out together towards the volcano, Revvit in his usual place on Ty's head.

It wasn't long before the lava pits came back into view and everyone just took a moment to enjoy the view of such a build as they had never achieved before that day. Ty felt Revvit adjust himself into a more secure position as they neared. He slowed his pace to allow the others to move ahead them before bringing up what he was sure was on the Reptool's mind at that particular moment.

"Rev?"

"Yes, Ty?"

"You're not going anywhere this time. I promise." There was amusement and a sincerity in his voice that put Revvit a bit more at ease. It also helped that Ty continued towards the pits at a subtly careful pace, and that he decided to come to a stop in a position that put the other Dinotrux between them and the lava.

"So, what's the plan?" came Dozer's gruff voice. Everyone automatically looked at Ty and Revvit, waiting for them to do their thing and explain what they had come up with.

"This will be tricky." Revvit began. "What we are making is small, so it is imperative that we are very precise."

"You mean WE will." Ace interrupted. "You're going to let us handle this one Rev."

Revvit was willing to concede this point to Ace as she was not wrong. "Of course. Never the less, this will be a very small part to forge so the margin for error is on a scale that we are not used to encountering on our usual builds."

The Trux could see the sense in that, even though they didn't like the idea of not being able to help. Skya wasn't about to sit on the side-lines though. "OK, fair enough. We will handle the lava and any other heavy lifting we can help with and we'll leave the details to you guys."

The only response she received was an "mmmhmm" from Waldo.

Dozer began clearing a space for the tools to work while Skya and Ton Ton unloaded the parts that they had brought along.

"Dude, Tool parts are so tiny!" Ton Ton said in amazement. The Ankylodump had been carrying what few supplies they would need, including materials to hopefully patch any damage inside the tail, and the tiniest pins and screws that Ton Ton had ever seen.

"Makes sense. Tools are pretty small." Skya reasoned. "Just be careful we don't lose anything. It would take us all day to find these things."

"Sure thing Skya." Ton Ton cheerfully replied. He was serious about being careful with such an important load, but once his bed was empty he was gonna ramp so hard he'd hit the clouds!

Meanwhile, Click Clack, who had already donned his orange safety glasses, was working up the courage to remove the damaged plate. Revvit faced his friend with an earnest expression. "Click Clack, do not worry. You can do this. Just take a deep breath and take your time."

Click Clack did as he was asked and slowly took a deep and very shaky breath. It didn't take away his nerves about what he was about to do but he did at least feel ready to give it a try. It also helped a great deal that Revvit had such trust in him to be able to do this.

Revvit turned to give a reassuring smile to Ty, who couldn't quite return the gesture. Instead, he couldn't help but ask, "Rev, are you sure you're- "

"Yes, Ty." Rev assured patiently. "I am OK."

Ty sighed. "It's just… Are you ready for this?"

"Yes. I believe I am. Do not worry, everything is going to- "

"be fine?" Ty huffed.

"Actually, I was going to say that everything is going to work out OK. It may not look like it but they know what they are doing."

"Oh." Ty looked sheepish for a moment. "I'm supposed to be the one reassuring you."

"And you are doing so Ty. To borrow from a T-Trux that I know, you have all 'got this'."

The two shared a smile before Revvit went to lay down in the cleared workspace where Click Clack and the others would work. After another deep breath from Click Clack, and just a few moments work, the plate had been taken off and the full extent of the damage was revealed.

Click Clack put the plate down and frowned at the newly exposed space. He used his tail spray to send a blast of air into the inside of Revvit's tail. When he did, there was a burst of metallic dust and tiny shards that filled the air with a shimmer, causing an 'ooo' and 'ahh' from most of the group, including a surprisingly enthusiastic "shiny" from Dozer.

Ace quickly broke the moment of wonder though. "Well that's not good."

Ty had noticed a distinct lack of reaction from Revvit himself. "Revvit?"

When he got no response the T-Trux lowered his head for a clear look, alarmed to see that Revvit was no longer conscious. "Revvit!" he exclaimed, moving to nudge him, but at the same time not wanting to move him under such delicate conditions. Ace checked him instead and after a quick assessment she announced that Revvit was fine, just passed out.

"Probably for the best." Skya said. "I wouldn't wanna be aware of my inner workings being exposed." She shuddered at the idea.

"What are you saying, you get fixed up all the time." Dozer argued.

"Yeah, not with outer bodywork completely gone I don't." retorted Skya.

Dozer considered the idea of it, of not having the protection for some of the most important parts that made a Trux, or Reptool, work. It sounded terrifying, not that Dozer was going to let Skya see how rattled he was by that thought. So, he simply shrugged and conceded with an offhanded "fair point."

Meanwhile, Ty was becoming visibly worked up at the fact that Revvit was so…still. Even when asleep, the Reptool would talk in his sleep and shift, his brain never really slowing down to rest. It was unnerving to see him like this.

Waldo scrutinised the debris that Click Clack had displaced. "Metal splinters. Probably from the bit that got stuck and caused the grinding he mentioned about." And if they were left behind in there they undoubtably also made it worse."

"Like the sparking when he tried to spin his tail!" Ace realised.

"Worse than that." started Waldo. "These metal splinters are razor sharp. They've been rattling around in there since earlier this afternoon."

There was a collective wince from the Trux as they realised the implications of that. Ton Ton summed it up best with a solemn "Ouch, Rev dude."

Ty's expression deepened from worry to anger at the idea that Revvit had probably been in pain all this time and had said nothing about it. This time Skya wasn't the only one to notice the T-Trux's shifting mood but there was no time for anyone to say anything because at that moment Revvit let out a quiet groan and opened his eyes.

He blinked a few times as his optics adjusted to the lighting that was definitely not their cave where he usually woke up. It took a minute, but he soon remembered what had happened. Then he realised that he felt a strange chill in his tail where it was exposed to the air, and that although disconcerting in its current condition, the pain had noticeably diminished.

"Don't move if you can help it," came the oddly calm and in control voice of Click Clack. "We took the plate off and I've cleared out a lot of metal shaving. We'll have you fixed up in no time."

Revvit didn't say anything but his eyes widened in alarm at the mention of the shavings. He only allowed himself a moment of panic before taking a deep breath of his own and settling down to remain still until the work was finished, trusting in his friends' abilities.

From his position Revvit blinked up at Ty for reassurance, only to see the same gear wrenching expression of worry and anger on his bigger friend's face. Another conversation to be scheduled in the very near future then, he thought as his eyes drifted shut again.

"He out again!" Ace called. She had been watching Revvit closely and had seen the silent exchange between her two friends but chose not to say anything. She knew they would sort out whatever was going on between them later at a better time.

"Let's get this done before he wakes up again," Skya said as she and Ace took the plate over to the lava to melt it down while Waldo and Click Clack measured and carved out a mould in the space that Dozer had cleared.

Without hesitating Ace dropped the tail plate into the lava with a quiet mutter of "No turning back now." After a few minutes Skya retrieved the molten metal and quickly but so carefully poured it into the mould where Click Clack had been triple checking the measurements and Waldo was ensuring it was flat and clean. Time seemed to drag as they waited for the metal to cool, waited to find out if they were going to be able to fix their friend or if they had made the situation much, much worse.

Ty was still watching over Revvit's very still form while Click Clack fixed a loose air line and double checked there was no other damage. Skya remained nearby in silent support, while Ton Ton and Dozer had moved away to burn off some of their energy. Ty would have gone with them to work off the building anxiety threatening to overwhelm him but there was no way that he was going to leave Revvit's side until he knew that he was going to be okay.

Finally, the new plate was ready, carefully lifted out and brought back to Revvit to be placed back where it belonged. It fit perfectly, and once it had been secured back into place there was a moment where everyone remained still, waiting for something to happen.

But nothing did.

There was no movement from Revvit. Ty moved closer to see if the Reptool would stir and stopped just short of nudging him with his snout. But Revvit still didn't show any signs of waking up. Click Clack, Ace and Waldo approached and gave him a nudge instead.

"Rev? Come on Revvit, you can wake up now." Ace was already thinking up ways to rouse her friend, some of which included some kind of crazy stunt and at least two involved some very cold water.

Meanwhile Click Clack was double checking Revvit's tail while Waldo circled around to see if there were any obvious signs of other complications. When nothing turned up, they looked to the others with no answers to the current problem.

"E-everything seems to be back in place on his tail."

"And I can't find any other damage. There's no mechanical reason that we can see for Revvit not waking up."

Skya lowered her head towards Revvit. "Maybe he just needs to rest?"

"Would it be okay to move him?" Ty asked anxiously. He preferred the idea of Revvit being back at the garage in relative safety away from Skraptors or Skrapadactyls. Not to mention having all their tools and parts close by, just in case.

"I don't see why not." Waldo stated. "Skya, you should use your hook to lift him into Ton Ton's bed- "

"I can carry him." Ty interrupted.

Trying to console him, Ace moved over to Ty. "Sorry big guy, but it's probably safer if we transport Rev in Ton Ton's bed where he'll be more secure."

"If we can get Ton Ton to move like a normal Trux instead of jumping off of everything he sees." Skya pointed out.

"We'll ride with him and make sure he's ok," Ace quickly reassured Ty.

"I guess that makes sense."

Some time later, Ton Ton and Dozer had re-joined the rest of the gang and been caught up with what had happened. Ton Ton had listened attentively when he had been told that he would be carrying the Reptools carefully back to the garage and had made no complaint about not being allowed to throw himself off every available ramp along the way. Dozer had scoffed at that.

"Hey, I can be careful when I need to be!"

Ton Ton had sounded so sincere, but that still hadn't stopped Ty from following alongside on the way back close enough to start making the Ankylodump nervous.

"Er Ty, I get that you wanna keep an eye on Rev-dude but we're gonna start trading paint soon if you don't give me a little space to move."

"Sorry Ton Ton." Ty looked abashed and backed off a couple of extra metres as they continued around one of the many large rock formations and then out into the more open areas that meant they were nearly home.

The Garage soon came into view, but everyone was still on alert in case of attack from Skraptors, Skrapadactyls or worse, D-Strux. They made it back to the Garage safely just as the sun was sinking below the horizon and took Revvit back to the area where the other Reptools had first looked at his damaged tail. Once he had been gently placed back onto solid rock without stirring, he was checked over once more while the Trux gathered around again. Ty's mind flashed back to earlier that day when Rev had admitted his discomfort at being so closely examined by everyone. He felt certain that his best friend would be very uneasy with the intense study that he was currently under.

Ty was brought back to the room when Waldo announced that he knew why Revvit hadn't woken up.

"Its his air pressure. It must have dropped too low. Rotilians have a compressor so that they can take in air and use it to power the airbrush in their tails."

"That's also how we fire the bits from our heads and backs too." Click Clack added.

"So how is the low air pressure stopping Revvit from waking up?" asked Skya.

"Its an important part of a lot of systems for a Rotilian Reptool. Too many to go through them all. But if I'm right then Click Clack already fixed the problem when he repaired the air hose in Revvit's tail. All that's left to do is wake him up."

An outraged "Are you kidding me!" from Dozer broke the stunned silence that followed. "We can't wake him up and you're suggesting we fix that by waking him up?!"

"I'm not sure I follow either dude. How is that even going to help?"

Waldo was expecting questions, though not such loud questions. "If-no, when we wake him up, we just need to get him to stay awake and breathe in deep for as long as he can. That should get his air pressure back up and he'll be ok."

"That actually sounds really easy," Skya said doubtfully. "How do we wake him up though?"

"Oh! I have an idea!" shouted Ton Ton. "I'll go get some water!" and he zoomed out of the Garage before anyone else could say anything.

While they were waiting for Ton Ton to return Ace turned to Waldo, "That was amazing Waldo. And Click Clack, you've done some amazing work today."

"Thanks Ace. But I'll be happier when Revvit is fielding the questions and ideas." Waldo really hoped that he was right about his theory. If they couldn't wake him up…

The silver Wrench tool glanced over at Ty, who was nervously spinning his treads, and lowered his voice so the T-Trux wouldn't overhear, "What do we do if we can't wake up Revvit?"

Waldo shifted uneasily. He had already thought about that but hadn't wanted to mention it unless it came to it. "If we can't get Revvit to raise his air pressure himself then there is a way that we could do it ourselves."

Knowing that Waldo would have had a good reason for not mentioning this before, Click Clack was afraid to ask. But he had so far managed to achieve several things today that he normally wouldn't have, so he asked anyway. "W-why don't we just do that then? Wouldn't that be easier?"

"If we get some thin tubing, we could put it into Revvit's mouth and pump air into him that way."

"But," prompted Ace.

"But the tube would have to go down as far as the compressor. The risk of causing irreparable damage is high and if it does work then Revvit will wake up before we can remove the tube. And we would have to keep him completely still until the tube is safely taken out."

Ace didn't know what to say. Click Clack looked like he was about to lose his bits.

"It's a last resort option. I don't want to try it unless we really have to."
