Who is Bugs Potter?

Who is Bugs Potter? When he was last seen, he was wearing a moustache and running out of a crowded rock club. Then, he was spotted dressed as a telephone repairman, trying to break into a glamorous movie star's hotel suite. Next, he was observed playing the drums at the high school band festival rehearsal.
Who is Bugs Potter and why is he doing all those wild things? Maybe he's just crazy or maybe he's a star....
