Pac-Man and the Ghostly Adventures
No Pets Allowed Especially Monsters!, Pt. 1
S1 E3:
When Betrayus can't defeat Pacster (now known as Pac-Man), he clones a bunch of monsters to create an army that Pac-Man can't eat. Inky, Blinky, Pinky, and Clyde warn him and he uses the berries against the monsters. But one monster saves him when he runs out of berries and they want to keep as a pet but only one problem: no pets allowed in the dorm.
