A red underbelly stretches from its abdomen to the bottom of its jaw. Fukamaru has two horns that resemble jet or plane engines, each with a light blue stripe in the middle. It has a single light blue stripe wrapping around its back. On top of its head is a dorsal fin, which has a notch on it for the male.
