Chapter 1:
Retroville:
Jimmy Neutron, Boy Genius, was working in his lab, trying to find his missing friend, Sheen. "I should've known Sheen wouldn't understand the notes," says Jimmy.
Jimmy's friend, Carl enters. "Jimmy, have you found Sheen," asks Carl.
"No luck," says Jimmy.
"NO," shouts Carl, "SHEEN WILL BE LOST FOREVER AND OUR TRIO WILL BE BROKEN AND WE'LL NEVER BE THE THREE AMIGOPS AGAIN!"
"You done," asks Jimmy.
"Sorry," says Carl, "I'm just worried about Sheen."
"So am I," says Jimmy, "but I won't give up!" Jimmy then sees something. "Wait... we have to go outside!"
. . .
Jimmy and Carl get outside and see a wormhole and it's erasing all of Retroville. "Jimmy, what is that," asks Carl.
"Some kind of wormhole," says Jimmy, "but instead of sucking up the entire town, it seems to be erasing everything!"
"Then can we just redraw it," asks Carl. Carl then starts to disappear.
"Carl, you're being erased," says Jimmy.
"Awe, I'm allergic to nonexistence... at least I think I am," says Carl. He then disappears.
"Carl," says Jimmy, "Goddard, Flycycle mode!" Goddard then disappears. "NO!"
. . .
Everything in the lab was disappearing, but Jimmy managed to get the Astrocar. He drove it through Retroville. "I have to find somewhere where I can fix this!" Jimmy then sees his parents. "Mom, Dad, get in the Astrocar!"
"You say something, Jimbo," asks Hugh. Then both of Jimmy's parents disappear.
"Mom! Dad!" Jimmy continues, then sees others disappearing, Miss Fowl, Nick, Butch, Principal Willoughby, Sam, Professor Calamitous, actually, Jimmy didn't mind that one. "Wait!"
. . .
Jimmy then drove the Astrocar to his former rival, now sort of girlfriend, Cindy. "Cindy, everything's being..."
"What was that?" Cindy then disappeared.
Everything around Jimmy was disappearing. Jimmy checks the Astrocar computer. "Not just my town... all the planets as well! I'm losing my whole universe!" He then has an idea! "But there is still a universe I can go to!"
. . .
Luckily, Jimmy's wormhole generator hasn't disappeared yet. He then activated it and drove his Astrocar through it. "To Dimmsdale!" Jimmy was gone, but so was his universe!
