Wow, been a while since this thread has been used.
So you know Chuck E. Cheese, right? What about Grubb E. Gremlin?
Grubb E. is an alternate Zipp, dressed up in a barber shop singer's outfit.
He's joined by Cap'n Clamp, the animatronic Silurid (the First Mate) who plays a mean banjo.
And finally Burt the Ticket Man who sells the tokens for Grubb E.'s games and exchanges tickets for cheap nick-knacks, and is way too ugly, dirty, and leering to be legally employed at a theme-park restaurant for children.
Other ideas include a ball pit containing a gator, a crazed chef selling pig-snout pizzas, and a pack of screaming gremlin children hypercharged on sugar, cheap pizza, and distracting games.
