Archie's Weird Mysteries (1999)

Season 1: Episode 5

Veronica is less than kind to Jughead for being different. She couldn't stand if she were different; nobody would like her anymore. Upon going with Archie to visit Dilton, Veronica accidentally zaps herself with a recently invented growth ray, which so far seems to have had no positive results. And then, Veronica begins to grow -- and grow -- and grow, and suddenly she's more different from everybody else than even Jughead is.
