The first time Plankton tries it, he discovers that a second dose of goo-goo gas turns the victim to an adult. He then revises it, but then it only turns Mr. Krabs and SpongeBob into seniors.
Then, he makes a scientific solution and finds out he is missing one ingredient: Baby Powder. That will make the Goo-Goo Gas work.
- The Goo-Goo Gas has three alternate packaging: a tank which Plankton can carry reading "GAS", a spray pump (spray pump holds Senior Citizen Spray), and his Baby Bombs.
