Age Change Gas

"Oh geez! After seeing Arnold, Carlos, D.A., Jyoti, Keesha, Ralphie, Tim and Wanda as teenagers, what I remember and what reminds me is that of a SpongeBob SquarePants episode, 'Goo Goo Gas,' and that's where Plankton used chemical weapons that would change SpongeBob and Mr. Krabs' ages, including everyone in the Krusty Krab into babies, and that's what I used to watch it when the world wasn't in deep chaos! Oh good grief. And now it's Werner Werman to be use this new type of gas that he got from Plankton after visiting the Chum Bucket since everything went topsy turvy now."

--Su Ji-Hoon, Alter des Gases

Age change gas (German: Alter Ändern Gas) is a type of gas that was once invented by Sheldon J. Plankton in a SpongeBob SquarePants episode, "Goo Goo Gas."

In When the Cold Breeze Blows Away, new types of age-changing gases are then invented by the scientists of the Werman Reich as part of chemical warfare.
