A Goby is a red fish that resembles a Cheep-Cheep. In fact, these two fish species look so alike they may be the same species with two different names. Regardless, the Goby species live underwater in Kero Sewers. Gobies roam the waterways, battling intruders who invade their territory. In battle, a Goby will lower its head and ram into its enemy. Additionally, Gobies have no special attacks. They are also weak against lightning magic.

Unfortunately for Gobies, the water of Kero Sewers can be drained, which is exactly what happened during the events of Super Mario RPG: Legend of the Seven Stars. Without water, Gobies flop around erratically on the dry ground. However, when engaged by an attacker, Gobies will use their fins as wings, allowing them to fly for short periods of time. While flying, Gobies attack the same way as they do when swimming.
