In the Wii, it's never specified what Sonic gets up to between acts when exploring the worlds, there is only cutscenes before and after boss battles ot when he moved onto the next world.

Sonic Colours for the NDS add more story between acts while one scene in Wii version of the story has Sonic wondering where Yacker went too, it could be he went to help his mother.
