The Grim Adventures of Billy & Mandy

S5 E6: The Grim Adventures of Billy & Mandy Season 5 Episode 6

When the mall's surveillance cameras capture Grim's silhouette attacking endangered owls, a naturalist named Corey Nebraska blames Grim for the attacks, while Mandy suspects Grim is sleepwalking again. Billy, Mandy and Nebraska follow Grim while he sleepwalks, but they realize it is actually Billy's mom, the one attacking the owls. When discovered, Gladys reveals her hatred toward the owls as she recounts the story on how an owl ate her pet rat, Sniffles, years ago. Billy's dad reveals that he was in fact the one who ate Sniffles merely to survive until lunch time.
