The antagonists are pastiches of The Muppets, being led by a literally pimped-out Kermit the Frog. He rides around on a Big Bird, and an Oscar the Grouch parody starts fighting with Black Dynamite and crew the second he sees them. Makes sense they'd live on Puppet Street.
When Leroy Van Nuys is first seen, his face is turned away from view and he is wearing nothing on his head. Then mechanical arms put on his mask, pimp hat and pimp feather just like he was Darth Vader.

A whore in the whorephanage seems to be a big fan of superheroes; she references Superman's slogan, comments she has a client tied up with spider webs, and crashes into the orphans' bedroom dressed up as Wonder Woman.
