While digging, he hits a rock midway between the Krusty Krab and the Chum Bucket. Plankton tunnels under the rock and discovers a beautiful underground cave and he uses it for a new restaurant that actually attracts customers. The cave dwellers there try to attack Plankton In the caves, but Plankton tames them to work for him as employees. The new restaurant . In those caves, the scenery is so amazing that the customers pay no mind to the quality of the food. There is also a gift shop there. Once Mr. Krabs finds out about this, he digs down to cave level to stop Plankton. The two go into a digging battle, making each other fall into a pit made by the other. While doing this, they become trapped underground for fifteen minutes until Spongebob rescues them. Plankton then uses a jackhammer to dig to the Krusty Krab, but ends up making the restaurant cave in causing the Chum Caverns, along with the Krusty Krab and all it's customers, and Plankton to fall to another cave and become trapped again.
