The Beetlepig was Mr. Antonio's only friend. He was initially believed to have swallowed Mr. Midnight , prompting Fran to kill him in order to rescue her cat. However, it turns out he had actually swallowed a Rat and not Mr. Midnight.
Beetlepig appears to be a giant wood louse with a pig's face and two small antennae with tiny black eyes. It has eight thin legs. Beetlepig is light brown (shell) and light pinkish brown (face and limbs) in colour.
