However, they are eventually kicked out by the zoo manager. Then, SpongeBob and Patrick are seen at the latter's house as SpongeBob is crying and Patrick is trying to comfort him. SpongeBob then blows a snot bubble which gives SpongeBob and Patrick an idea to create the Bubble Zoo. They begin blowing bubbles, but when Patrick names them, they pop which gives SpongeBob the idea to make the animals out of Extra Strength Bubble Soap. Then, the Bubble Zoo is opened with SpongeBob at the main entrance charging everyone a smile to enter and Patrick as the security guard, asking everyone to leave their sharp objects in a box.
SpongeBob introduces the Bikini Bottomites the bubble animals. Squidward wakes up, wears his gardening uniform, goes outside, and being eaten by a bubble sea monster. SpongeBob tickles the bubble sea monster, which lays Squidward as an egg until a bubble goat ate his gardening uniform, begins to scream, starts running, popping out of there cells, and being hanged from a bubble rhinoceros. The bubble rhinoceros begins to run and pops the whole entire bubble zoo, and the other bubble animals begins to run away which runs over SpongeBob. Patrick tries to stop them by using the bubble elephant's trunk to make as a hammer. He starts whacking the animals until the bubble elephant whacks Patrick.
The bubble animals went wild. Mr. Krabs is protecting his cash register and Plankton and Karen are surrounded by bubble penguins. While SpongeBob and Patrick are surrounded by the bubble animals which makes Patrick hides in SpongeBob's body and SpongeBob begins to yell which makes the animals free from the zoo to save him. The zoo manager tries to stop the zoo animals but they run over him.
The zoo animals have arrived. The bubble animals are trying to scare them. The sea monster begins to roar at them which makes the bubble animals to go inside the Extra Strength Bubble Soap jar. They returned to the Bikini Bottom Zoo to return the zoo animals. The zoo manager apologizes to SpongeBob for selfishly banning him from the zoo early, removes the ankle alarm from SpongeBob's leg, and let him play with the zoo animals anytime. He's impressed that SpongeBob put all of bubble animals in the Bikini Bottom Zoo. The episode ends with Squidward hanging his nose from the bubble rhinoceros.
