Marshmallowy Mweadows is a place in the Candy Kingdom first introduced in the episode "Fionna and Cake." Fionna and Prince Gumball go there on a supposed "date." The flowers are made of marshmallows, and there are also cotton candy trees. The ground also appears to be very soft and penetrable since Prince Gumball easily dives into it with no injury. There are also pearl pygmy skulls underground.
- An early storyboard of the episode has a cavernous dungeon that exists beneath the Marshmallowy Mweadows, thus making the location appeal to Fionna in multiple ways. In the storyboard, Gumball finds the pearl pygmy skull inside an iron maiden.
