Gunter

Gunter (voiced by Tom Kenny) is the penguin that most commonly accompanies the Ice King. The Ice King uses Gunter as his personal servant, whereas the other penguins working for the Ice King are essentially slaves. In truth, Gunter is the primordial cosmic entity known as Orgalorg and feared as the Breaker of Worlds.

In "Come Along With Me," Gunter used the wish-granting abilities of the Ice King's crown to "become" Ice Thing, taking on a form resembling their former master.
