The loud loudspeakers

Many, many light year away on the other side of the galaxy there is another planet. A planet that at the first look looks like our. But when you land you can see it is not. There is human being here but it is also other half human half animal being called mobiens and the planet is called Mobius.

Mobius used to be a peaceful and ruled by the good and caring Queen Aleena Hedgehog, that was, as you probrbly understand a Hedgehog. But one day the evil Dr Ivo Robotnik, thate was a human, attacked her castle. Thanks to an Oracle that had worned her about it. She was abel to flee and hid her kids at three separated families. After that she disappeared and nobody knows. When the kids, Sonic, Sonia and Manic, become older they reunited and vow that their mother will be found.

A prophecy say that when they found there mother the four will step forward and overthrow Robotnik and they will rule Mobius again. The kids is toring the world as a rockband under the name "Sonic Underground" locking fore there mother. And she knows that, but she also knows if they found her too soon it will seal their fate.

Enough with the introduction lets start the story.

The three siblings come out with their instruments; Sonic had the guitar, Sonia the keyboard and Manic drums. This was more then instruments, it was weapons too. They come from the magical stones around there necks.

"Hellooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo everyone" Sonic called and the crowd went wiled. Sonic suddenly noted something text to the scene. It was a fox kid not older then 10 with yellow fur. But the thing that he notes the most was tat the kid had two tails. He turned back too the audience. "Thanks too all of you to come and lets hope that old butnic is not coming, enough talk lets sing" and the band started play and sing.

At the same time in his fortress, the evil, mad and extreme overweighed scientist Dr Ivo Robotnik was sitting and tiping frantic at his computer.

"What are you doing your evilness?" Sleet, one of Robotnics employee, that was a wolf, asked.

"I am going to use thus dame Hedgehogs one way" the doctor said.

"how?" Dingo, another employee, and Sleets assistant, and, just as it sounds, a dingo, asked.

"You will see" the mad scientist said.

Back at the concert the Sonic Underground was finished with their first song.

"Old Butnic has not arrived yet" sonic said, "lets hope he has giving up and let us along this time." The public cheered "lets go to song nr 2" Sonic said. But just has they started playing an evil laugh was heard from the loudspeakers.

"Attention people of Mobius" the voice said, "this is your roller that speak."

"ro-but-nic" everybody said.

"How do you do this?" the fox next to the stage that sonic noted earlier asked.

"I have hacked in your loudspeakers and microphone so I can her you all and speak to you all" Robut…I mean Robotnic said. "And with this I am going to kill you all."

"What are you going to do?" Sonic asked "bore us to death with one of your speeches?" everybody laughed.

"No" the doctor said "dose anyone know what decibel is?"

"It is the way you measure Sound waves" the Fox said "to low and you can't her it. To high and you can get deaf"

"You are clever for your age?" the doctor said.

"If it wasn't from you I would have taken that as a complement" that two-tailed fox said. Everybody laughed again.

"What have this to do with us dying?" Sonia asked.

"Do any of you know at what point it get harmful?" The mad scientist asked

"At 180 your eardrums is bursting" Manic said. All stered at him.

"how do you know that?" Sonia asked.

"I don't know" Manic said "I just do."

"do you know at what point it is harmfull?" Robotnic asked.

"No" Sonic, Sonia, Manic and the two tailed fox said.

"lets finde out shall we?" he asked. Sudely a sound was hered from the loudspeakers. It get louder and louder.

"Everybody out" sonic screamed. Everybody left the aria. Everybody expect Sonic, Sonia; Manic and the Fox.

"What are you doing Kid" Sonic yelled "get out".

"I can't move" the fox said, "The sound is so loud that our body don't want to do the thing our brain want."

"You are clever for your age" Sonia said.

"That I take as a compliment," The fox said.

On a hill not long from the concert Queen Aleena Hedgehog was stnding at the scene infrot of her.

"I have to do something" She said "But what" but before she kud come up whit something a loud expotion was hered.

A big smoke cloud was seen in the sky. It comes from the area where the stage was up until now.

"I didn't expect that" Robotnic said "But this is better."

"What happened?" Dingo asked.

"The loud loudspeakers exploded" The doctor said. "And there is not a single living thing in the area but it is one on a hill near it, and I think I know who it is"

The Queen haf falling too her knees and crying "it is over " se sobbed, "My kids is dead and the prophecy will never come true".

On a hill behind her a silhouette of a figure was portrayed against the full moon standing in the hill. Or standing and standing it was floated some centimeter over the ground. He was short and had one of thus hats that Jesters haid.

"so it has bigan" the figur said "not as I have pland it, but maby for the better." And then the figur disappeared in thin air.
