Hocotatians bare multiple resemblances to humans, including expressing human-like emotions. Physically, Hocotatians have a humanoid shape, the main difference being a larger head-to-body ratio, and having much larger noses. However, their eyes are very different compared to a human's eyes, in that their shape changes for showing emotions because Hocotatians do not have eyebrows. In a "neutral" state, the pupil is heavily dilated, giving their eyes the appearance of being entirely black, which leads some people think they are actually closed. When surprised, the Hocotatian's pupils shrink and expose their irises, making them more closely resemble humans' eyes. This can be seen in a Pikmin 2 cutscene shown after completing the debt, and every time Olimar is hit in Super Smash Bros. Brawl.
