Walrusses are creatures that oppose Wario in the Wario Land: Super Mario Land 3. They look like actual walrusses, but carry a harpoon. Judging from their outfit which includes a pirate-like striped bandanna, it can be assumed that they are affiliated with the Brown Sugar Pirates, a band of thieves that shares a rivalry with Wario. They mainly occupy the watery areas of Kitchen Island, where they patrol underwater passages. If they spot Wario, they shoot a harpoon at him, which can eiter regress him to a former state, or kill him and throw him out of the level.

A walrus also makes an appearance in Donkey Kong for the Game Boy in the iceberg world. It is just a regular walrus without any weapons. It patrols across the screen protecting the key. If it gets into eye contact with Mario, it will charge at him with its fangs. Mario can stand on it, but he cannot pick it up like other enemies in the game.
