Stimpy

Stimpy was a humanoid male. At some point after his death, he was animated by the necromantic powers of Gern Blanston, serving with his fellow thralls Carol, Coral, and Fatty Arbuckle. As a companion NPC, Stimpy was played by Matthew Mercer, but he followed the instructions of Gern's player, Chris Hardwick.

Background
Stimpy was not related to Gern Blanston or his other thralls, although Gern did consider them all a make-shift family.
