He is first seen at a bar where most of the Gremlins where when humans evacuated Clamp Skyscraper and the Brain Gremlin was giving a TV interview with Grandpa Fred where the Gremlins were watching him on the TVs.
He wears a t-shirt with a logo similar to the Ghostbusters logo but with Gizmo in place of the ghost. He was with a gremlin who was reading the book "Dining After Midnight in New York", where the Gizmobuster shirt Gremlin was holding a very light-brown colored teddy bear and both gremlins were laughing about it. He presumably dies along with most of the other gremlins (except Greta) when they get electrocuted by the Electric Gremlin.
Gizmobuster is a parody of Ghostbusters.
