Appearance
Gunter is apparently very fat for a penguin, as Ice King has called him, "Daddy's little fatty", though this may only be a joke or a show of affection on Ice King's part. This is likely, since Gunter looks exactly like every other penguin in the Ice Kingdom. She looks like a regular penguin with big eyes, a navy blue back, and a white flat belly.

Behavior
Although Gunter is a penguin, he makes a "quacking" sound. It is shown the Ice King sometimes gets agitated by Gunter's actions such as accidentally breaking him video game or making a constant cry, but the Ice King seems to appreciate him company. he is very loyal to the Ice King, but even though he is Ice King's servant, Gunter occasionally wanders off.
