Uncle Grandpa (2013)

S1E9 Uncle Grandpa Ate My Homework

Uncle Grandpa arrives and, in a mix-up, devours a child's Egyptian diorama meant for school. To make it right, he assists the kid in bringing a genuine pyramid to class. However, this well-intentioned act backfires when he inadvertently awakens a malevolent mummy, setting chaos loose upon the world.
