Ah, a delightful kid-friendly joke with a spooky twist! Let's feast on this undead humor:

"What kind of cereal do zombies like? Kellog's All Brain."

I guess even the undead need to start their day with a nutritious meal! Just remember to keep your pantry stocked with extra cereals in case any hungry zombies come knocking on your door.
