Overload Ocean is a mechanized ocean on Planet Popstar and serves as the third level of Kirby: Planet Robobot.

General Information

Overload Ocean is an ocean that has been largely taken over by a marine port built by the Haltmann Works Company. Shipping containers, submarines, cranes, and other apparatus are found here. In addition to this, the company has established a research facility, a giant building made out of frozen treats, and underwater cities. With Robobot Armor's Wheel and Ice Modes, Kirby can race through enemies and build snowmen.

By collecting at least six of the 15 Code Cubes scattered throughout Overload Ocean, Kirby disables the firewall protecting the boss. He then meets and fights Susie.
