"Pet or Pests" is the first segment of the 119th episode of SpongeBob SquarePants.


One day, SpongeBob and Patrick are playing, when they land in a bush. They destroy it, and the two find a worm that lived in the bush. SpongeBob takes it home, and introduces him to Gary, which takes an immediate dislike to. They fight, and SpongeBob pulls them apart. Later that night, SpongeBob lets his new pet stay where Gary usually sleeps, and Gary is sent to the guest room, which he doesn't like. The next morning, SpongeBob wakes up and sees the worm in a type of pain. He runs to Patrick because he doesn't know what to do. They go back to SpongeBob's house and see that the worm had given birth to baby worms. SpongeBob and Patrick try and put Gary and Mrs. Wormsley together, but she attacks Gary again and Gary chases Mrs. Wormsley out of town on a bus, so SpongeBob is left to take care of the worm babies. He tries to sell them, but he fails, because the babies spit an acid onto the person's face. After trying to sell them to Mr. Krabs, and he said to take them out of his restaurant. SpongeBob puts them by the garbage, but the babies spit on him too. Garbage men come up and they are about to take the garbage away when they see the acid on SpongeBob's face. They see that it is a very rare type of worm, and Mr. Krabs comes out, hearing how it is rare and they would bring a lot of money. So, SpongeBob and Mr. Krabs sell the worms to the people of Bikini Bottom.
