Holpen looks like a light blue sea horse, with a black circle on its face, with eyes on it. It has a fin on its back.
- It could turn the circle on its face, which mean its eyes can rotate.
- It could fly, using farting bubbles.
- Holpen was named from Adventure Time's original creator, Pendleton Ward.
