Two Rivers Isle [NaWOWriMo] And don't you fall, when it feel like hell

Challenge: 1. Something happens and your character gains a superpower - Elfie can become a combustible supernova.

Elfie had had great fun with his new friends on the secret moon (Smoon). He had also met the Master Wizard of the place, who had liked the little boy so much that he granted him a little bit of cosmic power. Not only his speed was greatly increased, but, if he focused enough he could become a glowing ball of energy and explode, and then reassemble himself again. The focusing part, however, was tricky, because, if he did it the wrong way, series of strained toots happened from his other end. 

And he would have stayed longer, were it not for a chance encounter with an octopus-like tentacled being (that's, what I could gather from Kovertol's experience), who had appeared out of nowhere, interrupted the game of tag he had been playing with resident smoonians and snatched him. Next thing the little boy knew, he was rematerialized in an entirely different place. Right next to a huge, furry beast, who looked just as confused as he was. 

But Elfie was not the one, who would stay confused for long. He prodded the big thing with his snout and barked at him, inviting the fellow to introduce himself.
