The Iceberg Monster is entirely made of ice and, like its name implies, looks like an iceberg. It has a carved-out mouth and two eyes, and also two arms, which can be used to grab hold of ships if they get too close.
Not much is known about the Iceberg Monster since it is seldom seen in the series. However, it is known that it can camouflage itself into its environment, taking the form of a regular iceberg floating on the ocean. When a ship comes close to it, the Iceberg Monster will rise out of the water and attack it.
