39 Sandy, SpongeBob, and the Worm

An "Alaskan bull-worm" terrorizes Bikini Bottom, and Sandy volunteers to go after it because it ate her tail. SpongeBob keeps trying to stop Sandy from going, but she persists. They find the worm and Sandy successfully ties it in a knot and gets her tail back. SpongeBob reveals that the "worm" is actually the tongue of the real worm, and the worm is huge. Sandy and SpongeBob sprint away and it gives chase. They get to safety after the worm charges off a cliff and plummets down the chasm, then they head back home. Unbeknownst to them, Patrick and everybody in Bikini Bottom have moved the city to a new location at the bottom of the cliff so it will be safe from the worm. The worm then lands on top of the city and destroys it, emitting the word "Ouch."
