Sonic finished another fight with Eggman. It was just Sonic trying to stop Eggman from going into a cave and getting something that would help power his robots or something. Sonic got curious and went into the cave himself, there he found a glowy crystal thingy with someone (you) inside it. This was probably what Eggman was going to use to power his robots. Sonic let curiosity win and touched it. The crystal shattered and Sonic passed out. Sonic woke up, still in the cave. You were passed out on the other side of the cave.
