"Goo Goo Gas" is an episode from Season 5.





Plankton is at it again... he tries to steal a Krabby Patty frome the Krusty Krab, but like always, he fails. This time, Mr. Krabs puts him inside SpongeBob's head, and Plankton is launched off back into the Chum Bucket after a countdown. Frustrated, Plankton decides to go to the park to chill out and think of his next plan. There, he sees a mother and her baby, and his light bulb turned on! If SpongeBob and Mr. Krabs were to be babies, they would be weak, and Plankton would win for sure! When Mr. Krabs gets mail from the mailbox outside the restaurant, he spots a coin tied to a rope. It leads Mr. Krabs into a telephone box and Plankton sprays some "Goo-Goo Gas" on it and then Mr. Krabs turns into a baby and Plankton steals the Krusty Krab key. But Plankton cannot jump high enough to reach the door locks so he asks SpongeBob to do this for him. Since Plankton tells loud of his plans and he was heard by SpongeBob, he informs the police, whereupon Plankton is arrested, but flees (the police should use smaller handcuffs!). Plankton now wants SpongeBob to turn into a baby, but when he tries to he sprays the baby Mr. Krabs again with the gas, and he turns back into the regular Mr. Krabs and tries even more times. Plankton then realizes that when sprayed with a second dose of the gas, babies turn into adults. Plankton does not give up and starts a further attempt - this time however Mr. Krabs and SpongeBob are sprayed with Senior Citizen Spray. Plankton then tries to steal a Krabby Patty. Then, they knit a net which catches Plankton and various senior citizens take turns hitting him with their canes and walkers, foiling his plot once again. He then revises the gas which when he sprays everybody with to turn into babies, they stay babies! But first he needs to test it on someone. And who does he test it on but his own wife, Karen! After Karen becomes a calculator, Plankton goes to the Krusty Krab and turns Mr. Krabs into a baby. When he sees SpongeBob come out of the kitchen, he turns him into a baby. Plankton then sprays everyone in the Krusty Krab. Now, not only SpongeBob and Mr. Krabs are babies, but also Patrick, Squidward and other customers of the Krusty Krab. Baby SpongeBob then plays with the gas, turning everyone in the Krusty Krab back into adults, possibly because the process of destroying it reversed its effects on the babies. Because of the gas, Plankton turns into a baby, and is in a molecule asking for a diaper change.
