In a parody of Frosty the Snowman, Nigel Thornberry from The Wild Thornberrys narrates as Jimmy Neutron, Cindy Vortex, Sheen Estevez, Libby Folfax, and Carl Wheezer from The Adventures of Jimmy Neutron: Boy Genius all build a snowman that looks identical to Patrick Star. Jimmy decides that the thing to make their masterpiece better than ever is one of his inventions, a top hat-like device that can make inanimate objects come to life (The Spoofinator 4000). When he placed his hat on his head, Patrick says "Birthday Happy!"
At first, the kids have fun with Patrick, but within a minute, they grow tired of his antics. Since spring is a long way off, the kids have to come up with a plan to get rid of him. Jimmy decides that they'll create a wormhole in the space-time continuum and send Patrick to the future. Cindy suggests they just melt him instead, but no one takes her advice.
The kids send Patrick 70 years into the future. 70 years later, at the Retroville Retirement Community home, Patrick shows up to annoy the now-elderly kids again, while Cindy chastises Jimmy for his idea. Nigel, now a skeleton, shows up to confirm that this is the end of the story; Patrick then pokes him with the stick, causing him to fall apart.
A shorter version of this spot, usually run during the end credits of the shows, ends with the kids being so spooked by Patrick coming alive that they immediately start chasing him down.
70 Years Later
All the things annoying Patrick did were:
Using Jimmy as a sled.
Sneezing on Cindy
Making Sheen cold at night
Wearing Libby's clothes.
Poking Carl with a stick multiple times.
Happy Go Lively, the music from "Squidville" can be heard in the short.
