Crocodiles are reptilian creatures that make a brief appearance in the episode "Video Makers." Finn instructs Slime Princess to swing from a vine over the crocodiles and land safely. Instead, she lands in the water, and the crocodiles dive in after her. One of the crocodiles emerges from the water with Slime Princess kissing its snout.
Like many of the minor animal characters, the crocodiles sport a very traditional look: dark green, with long snouts and tails, and sharp teeth.
