Mezzka is a GoblinDevout in the Goblin Camp in Act One. He is initially hanging around the chicken chasing arena, chatting with Krolla about their replacement 'chicken', that being the Owlbear Cub.
Once a game of chicken chasing has concluded, he will begin to endlessly chase the cub around the camp, trying to keep it in one place. If the cub isn't at the camp or given its freedom, he will hang around at the center table with Tracker Puli and Sharp-Eye Mirg, occasionally going to the booze tub for a refill.
