Pet the Sonic Hedgehog
From Sonic Retro
Pet the Sonic Hedgehog is an unfinished Flash cartoon animated by Alexbt, with lyrics adapted by Kilometers Prower.
The music of the video is Brand-new World, from the rare Japanese CD Sonic the Hedgehog - Remix.
The idea of the film was that the Sonic Classic members would all be dancing, and the sprite of Sonic Sue would be singing. Then different things would happen during the course of the cartoon.
Due to the time and effort involved, and the fact that Alex sucks at Flash, the cartoon has yet to be finished. Perhaps some day, it will be.
