Frank's Beta Fish is a pet fish that has been held captive in the Chin Chin Hazard Bunker 19 by Frank while hiding from Chin-Chin with Red Dick. The only word that he was heard saying is "Please kill me!!!!", with a voice simalr than David Attenborough. He was seen living in a wine glass, as Frank was goofing around him. Although he sounds like David Attenborough, it is possible that this beta fish is, in fact, David Attenborough himself in a fish form, but then he was stuck inside this fish's brain, which it seems like he was freed after when the beta fish itself died.
