The Adventures of Sonic the Hedgehog

When Robotnik announces his intention to give up villainy, Sonic is therefore forced into retirement, and the offer of an all expenses paid adventure holiday from a town's grateful mayor seems like just a thing to relieve his and Tails' boredom. But - Shock! Horror! - The mayor was really a robot, and the entire island is populated by the duplicitous Robotnik's troops, and they are determined to upon bringing about the heroes' demise. Perhaps mercifully, this is completely bland.
