Michael is in charge of Pebble and the pets themselves, but since humans no longer visited them, he had to devote all his attention to Pebble, as it was the only pet he could care for. He's a toon with a somewhat unusual temperament. He gets very angry and starts yelling, but he's also quite kind and wants to change his irritable behavior. He tries to be nice, but accidentally starts yelling when he gets angry.
