The episode begins with SpongeBob and Squidward cleaning the Krusty Krab. Squidward finds an old Krabby Patty and tries to throw it away, but SpongeBob tells him all Krabby Patties should be wasted. He eats the patty, only to gag. Realizing Squidward was right, he chooses not to eat more after Squidward mockingly tries to give him more. When he goes outside, he meets a giant hamster named Cuddle E. Hugs and becomes friends with him.
SpongeBob and Cuddle E. Hugs do several activities until they go to SpongeBob's home to sleep. In the morning, Cuddle E. Hugs is gone, but when he eats the moldy Krabby Patty from earlier to make himself feel better, the hamster appears again. Afterwards, SpongeBob tries to show Cuddle E. Hugs to his friends, but nobody sees him as SpongeBob is hallucinating about the hamster.
Cuddle E. Hugs tells SpongeBob the secret that the moldy patty allowed him to see Hugs. He tells SpongeBob he should feed the moldy patty to the citizens of Bikini Bottom, so he goes to the Krusty Krab to sell tiny pieces of the moldy patty for free. After everyone eats it, they see Cuddle E. Hugs and start cuddling his soft fur.
However, he starts to eat all of them but in truth they are hallucinating and running around. When Squidward arrives, he sees the crazed citizens and is put off by the sight. He then decides to go back home, as the restaurant is crazy.
When the Bikini Bottomites wake up the next morning, they are angry at SpongeBob for doing this. Sandy tells SpongeBob to make a better imaginary friend before leaving with the mad crowd. SpongeBob eats more of the moldy Krabby Patty to ask Cuddle E. Hugs why he ate everyone. He says that he ate everyone as the E in his name stands for Eat. Thinking he's still hungry, SpongeBob makes Cuddle E. Hugs eat a leftover part of the moldy Krabby Patty, transporting him into a girl's bedroom in the surface world.
