The Marshmallow Kids are six marshmallows that live in the Candy Kingdom. They appear in the episode "Susan Strong." They refuse to run away from the Hyooman tribe, stating that "The Marshmallow Kids never run from a scrap!" Jake then accidentally sets them on fire as they run to fight. This sets the Hyooman tribe's hats on fire. The Hyoomans then rip off the hats, revealing they aren't human before fleeing. The Marshmallow Kids then shed their burnt skin. When Finn asks if they'll be alright, they reply that they'll just be gooey for a while.
One of them is later seen at the talent show during the events of "Five Short Graybles".
- They are particularly brave for Candy People, seeing as they ran right into the fight.
- A female marshmallow kid can be seen to the left of Fionna on the cover of Adventure Time with Fionna and Cake Issue 1.
