The Arctic sperm whale is a dark gray whale whose appearance is based on Pearl's. His eye is light yellow with a black pupil. He wears a purple shirt and a red scarf.
When the whale orders a Krabby Patty, Mr. Krabs makes Squidward deliver it in hopes that the cold Arctic will kill Squidward and make his art more valuable. However, SpongeBob helps Squidward deliver the patty. When the whale gets his food, it is covered in a block of ice and he says that it is cold, just how he likes it.
The book Nautical Nonsense reveals that Pearl has also visited the Arctic, meaning she could have a connection to this whale.
Clancy Brown, the voice of Mr. Krabs, voices the Arctic sperm whale. The Krabs family includes many of them, but this marks the first time he has voiced one.
