Once the three get back to the positive world, they begin to make their plan.
"What now?" Chad asks.
"We only have 24 hours until we're all mindless kids obeying negative future me!" Numbuh 4 shouted.
"Then we have to act fast. Anyone have a plan?" Numbuh 60 asks.
Wally and Chad shook their heads no. Suddenly, down the lane, a large device from the roof of a mansion begins to appear. Patton remembered the device that turned everyone into animals and decided that the new device would probably be similar.
"Numbuh 4, do you think that this new beam might be like the one Father used to turn us into animals?"
"Maybe…why? You have a plan?"
"I think I do…" Numbuh 60 said. "Chad, how good are you with technology?"
"I don't know, alright I guess?"
"Good enough. Listen guys, this is what we're gonna do…"
Numbuh 4 knocked on the door of the Delightful Children. The five opened the door angrily.
"What do you want, KN Dork?"
"Hey, uh, I have a question" Wally stalls.
"Can't it wait? We're about to turn the whole world into adults!" the five proclaim.
"No, this is important. Uh. Um…" Wally thinks of something while on the other side of the house, Numbuh 60 and Chad begin to sneak into the house. Silently opening a window and crawling in, they search for the piano that controlled the beam that turned everyone into animals, figuring this would be the same beam.
Once inside, they start to enter every room. After not finding the piano room after searching through five doors, they hear the Delightful Children start to close the door.
"Wait!" Numbuh 4 yells. "I…uh…have you seen Father's Pipe?"
"What!?" the five yelled.
"Yeah…I, uh, heard he lost it, and he's real mad."
"Oh no! We have to find it before someone else gets a hold of it!" the kids shouted. "It should be in his study…" they turned around, finding a startled Numbuh 60 and Chad down the hall.
"What's going on here!" the Delightful Children asked.
"Well…" Numbuh 60 said.
"Listen here, Delightful Dorks" Numbuh 4 said, "If you don't show us where Father's study is, the world will be filled with kids!"
"Whaaaat?"
"You see, a negative version of future me is turning kids, teens, and adults into brainwashed kids who do as he says. If you don't let us alter your animal-laser, everyone will become kids!"
"Oh no! We don't want that at all."
"Then show us where his study is!" Chad yelled.
"Fine, fine!" the Delightfuls agreed. Leading the three down a maze of halls, they finally reach Father's study, where his piano was. "This is where we set up the laser to turn everyone into adults."
"Can it turn everyone back to normal?" Numbuh 60 asked.
"Maybe…" the Delightful Children said. From there they got to work.
"Almost done…" they announced after a few hours.
"18 hours until everyone's a mindless kid!" Numbuh 60 yelled checking his watch.
"You know how we said we wouldn't want the world to be filled with kids?" the Delightful Children asked.
"…Yeah…?"
"Well, we wouldn't want to help the KND either!" they yelled, kicking Numbuh 60 onto the wall.
They began running out the room as Chad realized the machine still turned everyone into adults instead of normal people. They had just wasted six hours of valuable time needed to save the world.
"Great" Numbuh 4 said, "Now we'll all be turned into mindless kids for sure"
"With one beam turning us into kids and one beam turning us into adults, who knows what will happen!" Chad realized, "Either we'll be turned into adults, we'll be turned into kids, or the two conflicting rays will destroy the entire planet!"
"Chad, do you think you can rewire this?" Numbuh 60 asked.
"I can try, but it'll take a while."
"In the meantime, Numbuh 4, find us a ship. We may have to get off of this planet to avoid being affected by the rays."
"Got it" Numbuh 4 said, dashing out of the mansion. "Where am I gonna find a ship?" he asked himself. He decided to head down to Numbuh 2's secret hangar in his bedroom.
He arrived at Numbuh 2's house and took the route down to the hangar. Looking around, he found another S.C.A.M.P.E.R and hopped in. Before taking off, he noticed something in the hangar. Though most of it was filled with 2x4 technology, a desk was on the wall. It was a bit out of place, so Wally decided to look around.
Walking over to it, he noticed that it was covered with blueprints for more 2x4 technology. He looked at them, baffled. He searched through about a dozen before coming across one that caught his eye, titled "In Case of Emergency".
Looking over the description, he realized it gave a bazillion different ways to reprogram lasers, including a reverse switch that changed everyone affected back to normal.
"Perfect!" Numbuh 4 exclaimed, grabbing the blueprints and running back into the scamper.
Red lights and sirens started, with a voice of Hoagie saying "You have taken Hoagie P. Gilligan's property. Please return the item to the table." Suddenly all hangar exits closed.
"Oh crud Numbuh 2. You're always too over prepared."
Numbuh 4 stayed locked in the darkened hangar for hours straight, deciphering how he was going to get out of there with the blueprints. After hours of thinking, even passing out for three or four, he decided there was only one thing to do.
Turning the scamper on, Numbuh 4 aimed all weapons for the hangar wall and blasted them away. Flying out of the hole, he flew down to the Delightful mansion.
Landing in the backyard, Numbuh 4 hurried inside and found the study.
"Wally! What took you so long!" Numbuh 60 yelled.
"It's been 17 hours, you idiot!" Chad exclaimed, "We've gotten nowhere with this machine and there's only 1 hour until we're all mindless kids!"
"I was trapped in a hangar…" Numbuh 4 tried to explain, realizing more time passed than he thought. "Anyways, I know how to help with this machine" he tossed Chad the blueprints.
"Wow…this might be able to work!" Chad said, reading over the designs.
"You get working on this" Numbuh 60 said, "Numbuh 4 and I will be heading down to the Negaverse."
