Alaskan Bull Worm

The Alaskan Bull Worm is a giant worm that appeared in the SpongeBob SquarePants episode, "Sandy, SpongeBob, and the Worm". The worm is able to easily destroy property by eating it. It is one of the most humongous creatures in the series as its mouth is mistaken to be a giant cave, its tongue is mistaken to be a giant worm and its large enough to crush an entire city by itself.

At the Krusty Krab, SpongeBob gives everybody a description of the worm; he says it is big, scary, and pink and "all wiggly". Sandy says she can fight the worm, but SpongeBob tries to stop her numerous times, even through she refuses numerous times. SpongeBob and Sandy are later chased by the worm in the episode, until they lost the worm when it accidentally fell off a cliff and crushed Bikini Bottom. Although it was monstrous, it seems to have an ability to talk, as shown when he fell from that cliff and landed on Bikini Bottom (which was pushed to an area below the cliff), it said "Oooouch!", but it is unknown if it could say other words.

The Alaskan Bull Worm has appeared in two video games. First in SpongeBob SquarePants: Revenge of the Flying Dutchman, the worm was a boss while SpongeBob and Sandy were learning karate in the worm's cave. The only way to win is karate chop the dark blue breath back to the worm, and not the green one. Second in Creature from the Krusty Krab, the worm swallowed SpongeBob in the beginning of the level Alaskan Belly Trouble. The rest of the level involves Spongebob trying to escape the worm.
