After waiting and watching with their pets for visitors to come to the zoo, SpongeBob finds Jimmy, Timmy and B.O.B. watching the "Dumb Animal Channel" Timmy discovered on TV. SpongeBob takes a peak at it, and he soon gets addicted, too. Jenny appears with her pet and tells SpongeBob, Jimmy, Timmy and B.O.B. that the zoo is closing forever.
The five Nicktoons and their pets investigate and find plans to what is happening. They tell all the Nicktoons that if there are no more guests, they will be shipped out all over the world. Fanboy pulls out a camera he took from the lost and found at the zoo and suggests they make a commercial promoting the zoo to be broadcast all over Cartoon Land.
SpongeBob, Jimmy, Timmy and B.O.B. go and search for equipment they need to broadcast. Meanwhile, Sheen and his pet steals the position of director from Fanboy. Sheen attempts to pribe the animals to do amazing things, but fails.
When SpongeBob gets back, they start broadcasting. But Sheen wants the signal to be broadcast more than the 45-mile radius it will travel, so he increases the power. The satellite gets destroyed and all the animals think all hope of saving the zoo is lost.
But just as SpongeBob, Jimmy, Timmy and B.O.B. and their sidekick pets are about to destroy the HQ in order to protect their secrets, the zookeeper jokes around and opens the gates and visitors enter. It is revealed that the visitors were also addicted to the Dumb Animal Channel, and since the satellite carrying the show had been destroyed, decided to return to the zoo to see real animals.
