Mohmoo is a giant sea cow. It has a big round nose with a gold nose ring, cow-esque face and horns, green spots throughout its body, and also, due to its seal-like structure, an ability to swim easily.
Even being gigantic, it behaves cowardly, but it is very obedient to whoever controls it. It almost cried when it was ordered to fight the Straw Hats at Arlong Park, but it was warned by Arlong, which made it attack the Straw Hats. Its behavior has not changed even after two years. After seeing the Straw Hats again during the journey to Fishman Island, it quickly fled in terror, but the Caribou Pirates easily forced it to turn back by giving it a lump on the head.
Abilities and PowersEdit
Not much is known about its abilities, but it has a huge appetite that can scare away people.
Arlong Park ArcEdit
When it met Monkey D. Luffy, Sanji and Yosaku, Sanji tried to feed it, but ended up beating it up when it tried to eat Sanji together with the food.  Mohmoo was used to tow their boat to the island.
It was initially scared to face Luffy due to the previous incident and almost forfeited the battle. But, being threatened by Arlong, it tried to attack Luffy, only to be used in his Gomu Gomu no Kazaguruma, where Luffy spun Mohmoo around the area, taking out most of Arlong's forces. Mohmoo itself was thrown out of Arlong Park and in the process was knocked unconscious  making the people watching this astonished.
Two Years LaterEdit
Fishman Island ArcEdit
Sometime after the events at Arlong Park, Mohmoo wandered into the waters near Sabaody Archipelago where it was captured by the Caribou Pirates. They used it as a means of advanced sea navigation. By putting a collar around its neck they could use it as a harness and hook it to the front of the ship, allowing it to pull them.
After moving the Caribou Pirates' ship close to the Thousand Sunny, Mohmoo recognizes Nami, Sanji, and Luffy. It gets scared and swims away, pulling the ship with it and leaving Caribou alone on the Thousand Sunny with the Straw Hat Pirates.
