Mouth Mutant

Mouth Mutant is a mutant whose head is entirely covered with mouths and whose hands are also mouths. In 3012, Morris wanted to punch him in his big mouth and all his other mouths when he believed him to be the one Munda was having an affair with.

Production
In May 2012, Countdown to Futurama introduced Mouth Mutant through a character design (released on 28 May) and revealed some information about him - such as the fact that he had a fun line or two - through the fourth Futurama podcast (released on 29 May).
