“Which ghost ate too much porridge?”/“Ghouldilocks.”

The story of “Goldilocks and the Three Bears” is often given the pun “Ghouldilocks” (ghoul + Goldilocks) in Halloween jokes. A riddle has been cited in print since at least 2001 and 2003:
 
Q: Which ghost/monster/vampire/zombie ate too much porridge?
A: Ghouldilocks.
 
     
Wikipedia: Goldilocks and the Three Bears
“Goldilocks and the Three Bears” and the older still “The Story of the Three Bears” are two variations of a 19th-century fairy tale. The original tale tells of a badly-behaved old woman who enters the forest home of three bachelor bears whilst they are away. She sits in their chairs, eats some of their porridge, and sleeps in one of their beds. When the bears return and discover her, she starts up, jumps from the window, and is never seen again. The other major version brings Goldilocks to the tale (replacing the old woman), and an even later version retained Goldilocks, but has the three bachelor bears transformed into Papa Bear, Mama Bear and Baby Bear.
