Plot
The episode starts at a normal day at the Krusty Krab. Mr. Krabs is doing paperwork and is confused as to why his profits are down. He goes out into the restaurant to see Squidward making a sale, minus the price of a drink. Mr. Krabs sees everyone is drinking a thing in a bottle, including SpongeBob. He tells Mr. Krabs about the drink called the "Kelpshake". Mr. Krabs worries that people aren't buying drinks with their food, so he bans outside drinks in his restaurant, forcing the customers to leave. He goes to see what Plankton has done this time. He doesn't know Plankton isn't behind this. Plankton tells Mr. Krabs he has no idea what is going on because he was relaxing in a beach chair. Then the two try to steal a Kelpshake and discover what it is made of. They go to a Kelpshake stand and try to get Plankton to find out, and all attempts fail. That night they both try to enter but an alarm wakes up a guard worm who attacks them. The next day Mr. Krabs reluctantly buys a Kelpshake and goes to the Chum Bucket to analyze what is made of. Karen starts analyzing, but Plankton gets impatient and interrupts the progress of the analyzer. They find out that the drink is made of, simply, Kelp Juice. The two drink the shake and find it to be delicious, but they ignore Karen who says that there is another ingredient. SpongeBob also runs out of a restaurant covered in kelp. Then they go out and see that all Kelpshake restaurants are closed because their shakes contained a toxic ingredient. Two decontaminants revealed that it will take decades to get rid of the unhealthy toxic waste and they're sorry for whoever drank the stuff. Then Mr. Krabs and Plankton grow kelp all over their body. So Mr. Krabs gives Plankton a Krabby Patty and then chases him just for the fun of it.
