Melvins guest star in a forthcoming episode of Cartoon Network’s animated show Uncle Grandpa, which airs 8/4. In the episode, Lizzy’s band bails on her hours before a talent show performance and Uncle Grandpa helpfully enlists Buzz Osborne and Dale Crover to accompany her. Osborne appears out of a giant, womb-like pod that kind of looks like the silly Corpse Flower that everyone’s been talking about. Watch an animated Osborne and Crover save the day below.
