The Adventures of Sonic the Hedgehog

When Robotnik threatens to close down an orphanage and evict all the poor little orphans, Sonic and Tails enter Caninestein's car design in a race, in an attempt to win the prize money! But the robots, Scratch and Grounder are also competing, and dog Sonic and Tails all the way, until they realize that they may be replaced if Sonic is defeated.
