Mr. Fizzles

Mr. Fizzles is Garth Fitzgerald IV's hunting companion.

Overview
Mr. Fizzles is a sock puppet Garth uses during some of his hunts, namely for interrogating people who would rather stay quiet, such as children. He makes his debut in season 7 episode "Party On, Garth" when a witness to a shojo attack, Tess McAnn, refuses to talk, Garth summons Mr. Fizzles to speak in his stead. This convinces Tess to talk about the shojo that killed her mother.

In "Torn and Frayed" Garth is revealed to own a safe boat, Fizzles' Folly, presumably named after Mr. Fizzles.

Upon becoming a werewolf, it is unknown if Garth still keeps Mr. Fizzles.
