"Previously on Johnny Test, Johnny's Baby Brother was foiled at his attempt at homicide and getting rid of the entire Test family except for Mom and Dad. He was sent to an island with a robot Mom and Dad, where he now resides!" Baby Bot narrates. On the Island, Baby Bot is lying in a craddle when a pair of white khakis fall in front of him.
"What the-" he says as the pants shrink and force themselves onto him. "Well, they are stylish!" Baby Bot's eyes turn red and Baby Bot has a devilish look on his face.
"Next stop, Porkbelly to DESTROY JOHNNY TEST!" he says in a demonic voice.
Meanwhile, school has just let out at Porkbelly Jr High, and Johnny is on his way home, dragging his baby barf green backpack behind him.
"Ugh, I have SOOOO much homework. And on the WEEKEND?! Really, Teacherman!?" Then he got an idea. An awful idea. Johnny Test had a wonderful, awful idea. He runs up to the lab and punches in the code. Susan and Mary aren't home, so Johnny rushes in and grabs a device. He races back to his room, where he powers the device on. The device then zaps all of Johnny's homework, completing it.
"Wow, and it's even in my illegible handwriting!" Johnny says. "I love this!" Johnny hides the device under his bed, hoping Susan and Mary will never notice. Suddenly, a loud smash is heard downstairs. Johnny rushes downstairs to see an empty house. Johnny then races back up to the lab, where Susan and Mary are waiting.
"Johnny, did you take the Homework Helper 2022?" Susan and Mary yell just as Johnny enters.
Johnny exclaims, "Oh, so a magical device of yours disappears and suddenly I took it?"
"Yeah, pretty much" Mary says.
"Yes, I took it! But I think something is wrong. There was a smash downstairs, and now everyone is gone! Even Dukey!" Johnny says. Banging is heard on the door of the lab Susan and Mary check the security footage outside the lab, to see Baby Bot outside the lab.
"Wait, why is the Baby Bot back?" Mary asks.
"AND WEARING THE SMARTY PANTS?!" Susan yells. A flashback occurs to the Smarty Pants being disintegrated and hauled to the dump.
"How are they back? They were literal ASH!" Mary says.
"Maybe the belt found another pair of white slacks?" Susan suggests. "These do look slightly different" The lab door is broken down and Baby Bot enters.
"Knock-Knock, JONATHAN TEST!" he says demonically.
"Whoa, didn't see that coming!" Susan and Mary say in unison. Johnny runs up to Baby Bot and drop kicks him through the ceiling.
"I WILL BE BAAAACCCKKKK!" he shouts flying toward downtown.
"How did you do that? He's 259 pounds of tech and titanium!" Mary says.
"I have NOOO clue," Johnny says. "But that did hurt."
Baby Bot lands in Porkbelly Park like a miniature meteor, causing a small explosion. Panicked citizens run away screaming. One pedestrian is hiding behind a park bench.
"I've seriously gotta get out of this town!" he says, observing the pandemonium in the park. Baby Bot emerges from the pit.
"Oh, Johnny is SOOO going DOWN!" Baby Bot flies into the air and to the Test house. Meanwhile, in the lab, Johnny is standing on the platform in his Johnny X outfit, awaiting new powers.
"We're giving you new powers to help you DESTROY Baby Bot!" Mary says.
"Super speed, strength, invincibility, invulnerability, and laser eyes!" Susan says.
"Sweet! Now fire it up, psycho sisters!" Johnny is then zapped by a blue light as Baby Bot crashes through the window, landing behind the Test sisters. Baby Bot whips out his freeze ray and freezes Susan and Mary.
"Stop right there, Baby Bot!" Johnny X says.
"You look ridiculous!" Baby Bot responds. Dukey runs into the lab.
"Oh, look, it's the dumb mutt!" Baby Bot says.
"HEY! NOBODY CALLS ME DUMB!" Dukey proceeds to kick Baby Bot, only injuring his paw. Dukey whimpers.
"HAHAHA! FOOL!" Baby Bot laughs. Dukey presses a blue button on Susan and Mary's computer and hops on the platform. The computer counts down from 5 and zaps Dukey with a beam of light.
"This is too easy! Like taking candy from a-" Baby Bot is then punched in the face by a giant Johnny X.
"No fair, I didn't finish my monologue!" Baby Bot says as he transforms into a robot as tall as the lab.
"Whoa, didn't see that coming!" Johnny X and Super Pooch say. Baby Bot stomps on the computer, smashing it. Baby Bot is about to stomp on the (still frozen) Test Sisters.
"Nighty Night!" Baby Bot says, but Johnny X flies across the room and holds up Baby Bot's gargantuan foot. Johnny then throws Baby Bot through the wall, sending Baby Bot flying across Porkbelly. Meanwhile, on Bling-Bling Island, Eugene is tinkering with a necklace as Baby Bot lands on the table, destroying it.
"What the-" Eugene is grabbed by Baby Bot and chucked away. He turns his head 180° to see Eugene's minions. They all run away.
"I'm coming for you, Johnny!" Baby Bot flies out of Bling-Bling Island. Back at the Test house, Johnny X and Super Pooch are attempting to unfreeze Susan and Mary.
"Should we put them in the oven?" Johnny X asks. Super Pooch glares.
"Oh...right! THAT'S IT!" Johnny X says getting an idea. Johnny X proceeds to "power poot", unfreezing the girls'.
"That was disgusting," Mary says. Baby Bot breaks through a different wall.
"There's no way you can possibly stop me!" Baby Bot then gets zapped in the face by a laser. But the laser reflects off Baby Bot hitting Johnny X.
"Wait...that didn't hurt!" Johnny X says. Johnny X uses his tornado hands to blow Baby Bot out of the pants. Baby Bot immediately reverts back to his normal size.
"Wh-What happened?" Baby Bot rubs his head. Baby Bot sees Johnny X, Super Pooch, Susan and Mary. The pants charge at Baby Bot, but Super Pooch jumps in and chews the pants.
"Quick, grab the belt!" Susan says. Johnny X grabs the belt and hands it to Susan.
"You can turn back, now, you know?" Mary says.
"Oh...yeah," Johnny X says, turning back to normal. Susan smashes the buckle of the belt with a sledgehammer. The red light on the buckle powers off, indicating no life. Dukey burps.
"Now as for Baby Bot..." Mary says. Johnny throws a wooden box on top of Baby Bot and nails it shut with a nail gun.
"EXPRESS DELIVERY!" Johnny says attempting to pick up the box, but it's too heavy. Johnny hops onto the platform where he momentarily turns back into Johnny X.
"EXPRESS DELIVERY!" Johnny X says, picking up the box and throwing it through the roof. The house collapses.
"GIIIRRRLLLLSSS!" Hugh yells.
"Ooh, so close!" Susan and Mary say. Meanwhile, back on the Island with Mom and Dad-automaton, the wooden crate lands, smashing to bits. Mom-automaton picks up Baby Bot and proceeds to bottle feed him. Pan up to the night sky.
THE END...LIKE...FOR REAL THIS TIME.
