The Penguin With Flower first appears in the episode "When Wedding Bells Thaw." It was with the Ice King during his wedding and it lifts the veil of Old Lady Princess. It and Gunter appear as the two penguins in the ice penguin's Cut Out. It makes a cameo appearance in "Five Short Graybles," where it can be seen lying on the ground.
It looks like most penguins, only it's smaller, its beak is shorter, and it wears yellow flowers on each side of its head.
- In "Five Short Graybles," its beak is longer and blends with the other penguins, excluding the flowers.
- In Adventure Time Battle Party it is a playable character, which can be bought from the store as an alternate outfit for Gunter.
- In Adventure Time Battle Party it is called, "Lady Gunter."
