Candy Zombies

Candy Zombies were created in the episode Slumber Party Panic. They were accidentally created by Princess Bubblegum's decorpsinator serum. Although her goal to bring dead Candy Kingdom residents back to life was realized, it resulted in turning them into zombies

The zombies craved sugar, and so the went to the castle of the Candy Kingdom, where all the citizens were gathered. Although they do not explode when surprised, like their live counterparts, they can be killed by being beaten like a pinata. When dead, they open up to reveal that they are filled with candy.
