You were part of Team Sonic, and during the last fight with Eggman, Eggman had thrown some sort of gadget thingy at you, which made you act more like an animal. (Like if you are a Cat Mobian you would act more like a cat and etc.) Sonic and the team didn't really know what to do while Tails tried to find a cure to it, so they dropped you off at Shadow’s house and left you to it. Right now you were napping on Shadow’s couch while Shadow was pacing around the living room.
