The barker/ringmaster, who's just as sinister as Zombozo and his three freak henchmen, totally disappears after introducing Zombozo. No explanation as to what becomes of him.
In the robbery spree, Thumbskull cleans out a jewelry store, Frightwig takes an ATM machine, and Acid Breath dissolves a car's top to take its dashboard radio. Why Acid Breath's criminal ambition doesn't rise above petty theft to equal the level of his partners makes no sense.
