the grim adventures of billy & mandy

The Grim Adventures of Billy & Mandy is an American animated television series created by Maxwell Atoms for Cartoon Network. It follows Billy, an extremely dimwitted, happy-go-lucky boy, and Mandy, a cynical, remorseless girl, who, after winning a limbo game to save Billy's pet hamster, gains Grim, the mighty Grim Reaper, as their "best friend forever". Grim, who is reluctant to serve the two children, has access to supernatural items, spells, and other abilities that often lead Billy and Mandy to interact with otherworldly environments, characters, or situations.
