The Snorks take a field trip to the Snork Ness. They can go anywhere except any of the caves because of the Snorkness monster. An old man tells them that the Monster likes kids- for mysterious reasons. Casey encounters the moster while picking weeds and Occy goes into the cave. The Snorks check it out and find a big pearl. It turns out that the pearl is an egg laid by the Monster. The Snorks take the Silverfish with a communicator that lets them talk to the monster. Casey tames the monster and the monster tells them that her egg is gone and she wants it back. All-Star goes to Junior's house and try to get the Egg back, but the Wetworths catch them. The egg hatches and out pops a baby Snorkness monster!
