The Last Resort

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.
