The Temmie's have gone feral in the Horrortale world. They're resorting to cannibalism. Their voices should be high pitched, but crazed. 

The Temmie's only have about 2 short lines, which is why the audition lines are all from the game. It's not a paying role because it is so short. If you want to be a feral Temmie though and help with the project, this is a good role for that.
