One day, Toothless was bored. He hadn't gone flying with Hiccup for ages (well, to him it felt like ages) because Hiccup was spending all his time in the forge making new tailfins. Which would be fine if they ever actually got used, Toothless thought to himself angrily. All Hiccup seems to do these days is work in the forge. Soon, people will have to force him to do anything else - wait a second, THAT'S IT!

Toothless crept off the stone slab on one side of Hiccup's room and started patrolling Hiccup's bed in circles, while Hiccup slept on, completely oblivious to everything going on around him. Toothless fought to keep a small smile off his face; this was going to be fun - well, fun for him anyway. He didn't think Hiccup would feel the same way. I guess the answer to that will have to be a resounding no, Toothless thought to himself. But who cares, this is going to be hilarious!

Toothless was just about to wake up the peacefully snoozing boy, but suddenly had qualms about it, but shook them off because he didn't know why he felt so nervous. But then he thought of how great it would be to go flying with Hiccup, and he came to a decision.

Toothless decided that instead of tickling the boy until he gave in and got up, he'd simply scare him witless. Toothless figured that if he scared him well enough, Hiccup would fall out of bed due to the shock and subsequently agree to go flying because he couldn't go back to sleep after. Perfect, Toothless thought.

He started pacing round the bed looking for a good hiding place. He later gave up on the idea, mainly because he was far too big to be able to hide anywhere and because in his opinion, a good scare prank doesn't need the prankster to find a hiding place at any point. As long as somebody winds up getting scared senseless, it means that your prank has worked, even if it hasn't worked the way you wanted it to.

He crept up to Hiccup's sleeping body, and weakly tugged on his prosthetic leg, deliberately not using his full strength so he didn't wake Hiccup too early. Hiccup mumbled a bit in his sleep, but continued to doze. But then he pulled harder, and harder, but still made sure that his efforts didn't detach Hiccup's metal leg. Eventually, Hiccup woke up, groggy and confused about why he'd woken up earlier than he'd planned.

"Whoa, what's going on?" Hiccup mumbled, slurring his words slightly as if he was drunk. Rolling onto his sides, he came face-to-face with a gigantic black creature that had green eyes and a gaping mouth lined with sharp white teeth! And it was standing right in front of him! "AARGH!" Hiccup screeched in an unnaturally high-pitched voice as he tried to get away from whatever had sneaked into his room. Unfortunately, his limbs weren't as coordinated as he wanted them to be at that time, and instead of quickly running out of his room before the enormous beast could eat him as an appetiser, he fell to the floor with a small thud. (It was only a small thud because, as we all know, Hiccup happens to bit a bit on the scrawny side.) As he lay on the floor in a half-dazed, half-asleep state, he heard laughter. Familiar laughter. He was about to shut his eyes and wait for the monster to eat him and put him out of his misery, when his eyes finally focused and Hiccup was able to see the 'monster' more clearly. He groaned to himself; he'd been pranked on a colossal scale. The so-called 'monster' from earlier had just been Toothless, his dragon. And from the sound of the laughter, Toothless had set up this little wake-up call himself. Hiccup sighed to himself. This was typical behaviour for Toothless when he wanted Hiccup to go flying with him.

Hiccup watched annoyedly as Toothless laughed hysterically at Hiccup for falling hook, line and sinker for his little 'prank'. "HAHAHAHAHAHAHAHA! HICCUP, YOU SHOULD HAVE SEEN YOUR FACE! FIRST YOU WERE ALL SLEEPY AND THEN YOU SAW ME AND YOU SCREAMED LIKE A LITTLE GIRL AND FELL OUT OF THE BED! THAT WAS HILARIOUS! AHAHAHAHAHAHAHAHAHA!" Toothless laughed at Hiccup's early morning fail some more, but quickly stopped when Stoick burst through the door holding a hatchet.

"HICCUP! What on earth has just happened in here?" Stoick yelled angrily, but stopped when he saw the borderline chaotic scene around him. His son, Hiccup, was mostly on the floor but with his feet (sorry, foot) still on the bed, and although Stoick couldn't understand dragons that well, he could almost swear that Toothless was on the verge of laughter. He paused to smile at the situation that Hiccup had gotten himself into. "Well, Hiccup, it seems that Toothless has tricked you into waking up again. Honestly, sometimes I'm not sure if I should punish him for scaring you so badly, or fetch him a huge barrel of that Icelandic cod he seems to love so much as a reward for getting you out of bed so quickly." And with that, Stoick strode out of Hiccup's room, leaving Hiccup staring at his father in shock. Toothless, however, was grinning smugly.

"You hear that, Hiccup? Your dad's thinking about getting me some Icelandic cod for waking you up. Does that mean he'll let me to do this to you more often?" Toothless obnoxiously asked, irritating Hiccup even more than the wake-up prank he'd just pulled. Hiccup was just about to say something back before he remembered the last time Toothless woke him up early, and smiled a wistful smile at the memory. Unfortunately, Toothless noticed it. "Uh, Hiccup, what are you doing?" he asked. Hiccup suddenly remembered where he was and passed it off as being a joke he'd just remembered. To throw Toothless off the scent, Hiccup quickly asked, "Do you want to go flying now? After all, that is what you woke me up for, isn't it?" Toothless quickly agreed with Hiccup's idea, since he had only become more restless after pulling off his wake-up call prank and needed to go flying urgently. So Hiccup got changed, grabbed Toothless' saddle and went flying for three whole hours. Toothless, obviously, was having a blast, but Hiccup was too busy thinking about how to get revenge on Toothless. The last time Toothless did a prank like that, Hiccup tickled him until he begged for mercy and (eventually) apologized. Hiccup later told him that if he woke him up too early ever again, he'd tickle him again, and possibly tell the other dragons about his weakness. Luckily for Hiccup, he got plenty of time to think while resting under a tree in a deserted island. Unlike the last island he'd visited when alone with Toothless, this island had loads of plant life and a couple of very annoying insects that stung him a few times. Toothless had taken that opportunity to sleep under the sun.

I don't get it. Why would he do a wake-up prank again, especially after I taught him a lesson for it the first time he did it? Hiccup thought to himself. Toothless is a member of the Strike class of dragons, and Strike class dragons are well-known for their accuracy and intelligence. Why would he do something that he knew the consequences of all too well? Then Hiccup had a brainwave. He'd only do it if he didn't know what would happen if he did! Toothless must have forgotten about the last time I got my back on him and woke me up early to go flying! Then he smiled. But on the bright side, at least I get a chance to get him back for it. After all, if you want your enemies to get their revenge on you, make sure you go to sleep first, which is exactly what Toothless has done. Lucky me.

Grinning devilishly, Hiccup circled Toothless until he could find a ticklish spot that he'd left vulnerable to attack. It turned out that there were several; Hiccup had never really noticed it before, but Toothless usually slept with the bottoms of his wings ever so slightly off the ground, leaving his stomach and sides almost completely unprotected. Still smirking slightly, Hiccup started looking around for something to tickle Toothless with, but all he could see on this part of the island was pebbles, trees and sand. He was becoming more and more frustrated, and was just about to run out of ideas when he unwittingly stumbled on four young wild yaks and some wild honey that the yaks simply wouldn't stop licking. Hiccup had an idea. Since the hive was quite literally dripping with honey and for some reason didn't have any bees flying around near it, Hiccup decided to take a few handfuls of honey, lure the yaks away with it, and smear it all over Toothless. After that, he'd just have to wait, but at least his patience would be rewarded later.

Using a long spool of strong, thick rope and a small, sharp knife that had been conveniently left behind by an ancient shipwreck, Hiccup tied the now restless baby yaks to a tree and started smearing Toothless with honey, being careful to smear most of it over his stomach and sides, but making sure he didn't wake Toothless up too early. Toothless grunted a little from the slight discomfort, but otherwise didn't notice a thing. Finally, Hiccup stood back and admired his handiwork. Toothless was now liberally coated in honey, from his scaly feet all the way to the top of his head. After tying Toothless' tail and back legs to a different tree with a concealed rope that Toothless wouldn't be able to see, Hiccup made the decision to release the yaks, who would probably feel hungry after seeing so much honey on one dragon. After untying them, they quickly ran over to the sleeping Night Fury and started to lick the honey off him, making him wake up and start giggling almost immediately. The yaks had obviously gotten to work, and they were doing their job well.

"Hahahahaha! Whahahahahahat's going on? Why are these yaks licking me, and why do I feel so sticky? Hahahahahahahaha! Hey, knock it off! Hehehehehehehe!" Toothless sniggered, as the yaks continued licking the sweet honey off him. Hiccup grinned at the scene.

"Toothless, you're covered in loads of sticky honey, and those yaks want to eat the honey, so they're licking it off you bit by bit. It'll stop once they've licked all the honey off you, which should take a while," Hiccup coolly answered. "After all, you are covered in the stuff."

"Ahahahahaha! How do you get them to stohohohohohohohohop?" Toothless giggled, trying to squirm away from the baby yaks as they dragged their small, rough and unbearably tickly tongues down Toothless' defenceless tummy and sides, making him laugh harder than before. After just one session of tickle torture, Hiccup already knew which places his dragon was most ticklish.

"BAHAHAHAHAHAHAHAHAHAHAHAHAHAHA! HICCUP, HELP MEHEHEHEHEHEHE! HAHAHAHAHAHAHAHAHAHA!" Toothless laughed, as two of the yaks had settled for licking his sides and another two licking his poor stomach and ribcage. Hiccup decided to watch for another minute or so, and then decided to tell him why all this was happening to him in the first place.

"Toothless, I think by now, I owe you an explanation," Hiccup began, smirking slightly. "Do you remember the last time you woke me up early?" Toothless nodded, or at least he tried to through his laughter. "Oh, you do?" Hiccup continued. "Do you remember me leading you to a deserted island and tickling you until you gave in and apologised for waking me up early that morning? And I suppose you definitely don't remember me telling you that if you did this again, I'd tickle you again, do you?" Toothless was so surprised, he tried to hold in his laughter for a few seconds, but failed miserably. "Oh, and the reason why you're being licked half to death by a bunch of baby yaks? That was all my own work, to be honest," Hiccup shouted over Toothless' almost deafening laughter. "I found a beehive and these four baby yaks while you were asleep, and smeared it all over you while you slept away. Now these yaks will lick the honey off you, bit by bit, and they won't stop until they've licked you clean. This time, I'm not looking for you to apologise, not at all. Although I'm fairly sure that the yaks' tongues shall loosen yours! Enjoy it while it lasts, Toothless!"

"WHAHAHAHAHAHAHAHAHAHAHAHAHAHAT?! NOHOHOHOHOHOHOHOHOHO!" Toothless protested, but to no avail. The yaks simply didn't want to stop licking off all that honey, and as Toothless was quick to discover, he was tied to a tree by a piece of very strong rope that appeared to be dragon-proof. He didn't have any trouble guessing who did this to him. After all, there was only one person he knew who could tie knots like this. (Besides, the last time Toothless checked, you needed two hands and a full set of fingers to be able to tie knots.)

"HICCUP, WHY DIHIHIHID YOU TIE MEHEHEHEHEHE TO A TREE? I CAHAHAHAHAHAHAHAN'T MOVE FROM HERE! HAHAHAHAHAHAHAHAHA!" Toothless chuckled. That laughter increased by a lot as one curious baby yak licked the bottom of his back feet, particularly the area next to his sharp claws after a few drops of sweet, succulent, addictive honey dripped onto them. Any control Toothless may have had over the amount of laughter that was being heard was lost entirely after this moment.

"YAAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA! PLEHEHEHEHEHEHEHEHEHEHASE, NOHOHOHOHOHOHOHOHOHOHO MOHOHOHOHOHOHOHOHORE! I GIHIHIHIHIHIHIHIHIHIVE, HICCUP, OKAHAHAHAHAHAHAHAHAHAHAY! I GIHIHIHIHIHIHIHIHIHIHIVE! I'M SOHOHOHOHOHOHORRY!"

"Nice try, Toothless, but I'm not letting you get away with waking me up that easily," Hiccup laughed, collecting some honey that was about to drip onto the sand and rubbing it all over his dragon's poor, sensitive back feet, which made him tense up and laugh just a little bit more. The laughing started up again once the same baby yak started to lick both of his feet in turn, randomly switching from one foot to the other. The fact that the rope made sure that he couldn't move either of his feet made it so much worse for the hysterical Night Fury, who desperately wanted a release from the ticklish torture that he was facing at the hands of Hiccup (and the tongues of these baby yaks).

"AAHAHAHAHAHAHAHAHAHAHAHAHA! YOU STUPID YAHAHAHAHAHAHAK, DOHOHOHOHOHOHOHON'T DOHOHOHOHOHOHO THAHAHAHAHAHAT! IT TIHIHIHIHICKLES! HAHAHAHAHAHAHA! EEK! HICCUP, PLEHEHEHEHEHEHEHEHEASE CAHAHAHAHAHAHALL 'EM OHOHOHOHOHOHOHOHOHOFF!" Toothless begged.

"I don't think so, Toothless. I happen to rather enjoy watching people (and dragons) getting their just desserts. I just hope you feel the same way about it as I do," Hiccup replied, with all the calmness of a deadly snake just before it strikes you dead with a venomous fang to the heart. "Besides, you're laughing, aren't you? People only laugh when they're having fun, so you must be having fun right now."

"NAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA! HICCUHUHUHUP, GET 'EM TO STOHOHOHOHOHOHOHOHOHOP! STAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!" Toothless was finding it hard to speak by this point, and it took another half-hour of torture (sorry, punishment) for the Night Fury to pass out from laughing too hard. (Well, to be exact, he passed out from being out of breath and energy which is technically caused by laughing too hard, but we're getting sidetracked here.)

At least two hours later, Toothless had woken up and all the honey had been licked off him bit by bit. Luckily for Toothless, he was still out cold while the rest of the honey was being 'removed', otherwise he'd have passed out laughing all over again.

They sat there in an awkward silence, until Toothless sheepishly said, "Sheesh, Hiccup, I didn't know you could actually pull off such an elaborate revenge scheme. Remind me to never get on your bad side again."

"I've already done that, Toothless, but you forgot all about it til now," Hiccup grinned, poking him a few times in the ribs (or at least, where his ribs would be if he was skinny enough to have his ribcage poke through his rough, scaly skin, which he wasn't) and watched his dragon flinch from the light touches of Hiccup's fingers and try to hold in his laughter.

"Not again, Hiccup! Hehehehehe! Those yaks have tickled me enough! Cut it out!" Toothless protested, giggling at the light touches on his surprisingly sensitive, scaly skin. "Get off of mehehehehehe!"

"Oh, I know, but I'm getting you back for being so smug about pulling this prank off after my dad came to see what was happening, not to mention laughing in my face about it all. Remember, Toothless, never be overconfident," Hiccup grinned.

"Got it, Hiccup," Toothless replied. Then, after a pause, "Do you wanna go home now? Apparently the novelty of us staying outside for ages is wearing off, as far as your dad is concerned."

"Yeah, you're right. Let's go home." And as they flew home Toothless promised himself that he'd never wake Hiccup up early in the morning again, only this time, he was going to keep that promise.

So, what did you think? In the reviews section, a guest asked me if there was going to be a next chapter to "Dragons aren't ticklish - or are they?" This is my response to that review. TBH, I wasn't actually thinking of doing a sequel to my first story, but oh well, what's done can't be undone and all that! See ya!
