Generally Orco is found simply wandering around aimlessely, Donkey Kong can come up to Orco and grab on to her dorsal fin, Donkey can then ride Orco. Like Enguarde the Swordfish, Orco can smash through underwater barriers, and can also leap out of the water and reach extreme heights.

 * His apperance and name may be based on the Kirby boss Acro the Killer Whale.
