The Snorks are waiting for their latest copy of Seamonster Monthly magazine, but the mailman delivers a scientific magazine by mistake. In the magazine, it tells how the mythological monsters can be conquered by going to a castle. While the Snorks are having fun, a real monster does indeed come out! All-Star finds the magazine and finds out that he needs a key from the tomb of the mummy. In the tomb, All-Star gets the key and is pursued by a rock. All-Star gets out in time, and saves the Snorks in the process.
