Razz ma Taz, or just Razz for short, is a unused character from Jazz Jackrabbit. It is rumoured he was originally intended to be introduced in the Secret Files expansion of JJ2, but other than that it's unknown what role he would've served in the game.
Razz would have appeared as a NPC supporting character in Jazz Jackrabbit 3. According to the game's design documents, Razz is Eva Earlong's cousin who works as a inventor. The player would have to rescue him from inside of a giant whale's belly, after which he would help Jazz by making new vehicles and piloting them.
