A/N

Here's more of the story, but hope that veryloyalfan likes, as I kinda did a plot twist here.

Ami and her siblings manage to get the Regress-inator out of Rodrigo's hands, but AJ and Platyborg's brains have mentally regressed to that of a little kid's, so using the inator on them could damage them, but the only solution, is for them to grow up all over again.

I hope people like.

Ami saw Rodrigo programming the Regress-inator, but she growled, knowing this guy had hurt her father, not just by turning Kiki evil, and turning him into a kid again, but Rodney cackled, as he was fighting them, but Ami was mad, but Rodney was scared, seeing how powerful they were.

"You're going down, jerkwad!" Kero said tying him up.

Ami high fived him, as he and Yumi had found courage in themselves to fight, but Perry was able to get the Regress-inator back, but he along with Phineas and Ferb had taken care of Rodrigo, but they had to get back to Doof's apartment.

The little P-Borgs then deployed their wings, but Perry activated his hoverjet, as he along with Phineas and Ferb got in.

They then found the little P-Borgs in their home, but Perry smiled, seeing the little kid versions of AJ, Annie, Doof and Platyborg were asleep, as they saw Alt Doof smile seeing the Regress-inator, but were going to Doof's lab carrying the little ones.

"Please let this work, for badness's sakes!" he muttered.

A beam emitted, hitting Annie and Doof, turning them back into adults, but Alt Doof saw Doof stop him from firing it at AJ and Platyborg's younger selves.

"Let me check their brains out, before you fire." Doof said to his alter self.

Alt Doof wondered what his 1st Dimension self was up to, but Doof used a brain scanner-inator to scan their brains, but his dark blue eyes widened.

"Dr D, what's wrong?" Phineas asked.

"They've mentally regressed, into three year olds meaning if that thing is fired at them, it could hurt them.

They have to grow up, all over again." he told them.

Alt Doof was stunned, as he couldn't take a lot of Platyborg being a kid, but Doof could.

Perry then destroyed the inator, so nobody could misuse it.

"Wow, your Daddy and AJ are kids like us, now?

That's seriously cool, guys!" Tifa said.

The little Platyborgs were sleeping over at their cousin's house, while Doof was sorting things out, but Ami was liking the idea of her Dad being a kid permanently, but she wasn't going back to school for a couple of weeks.

"Maybe they can come to school, with us!" Ami said.

Kero knew his sister had found a playmate in the little kid version of their father, but hoped she wouldn't get him hurt.

"Maybe, guys." Yumi said eating cookies.

Tifa was getting crazy ideas, whispering into Ami's ear, as Ami laughed.

"Yeah, let's do it!" she replied.

She then became unseen, and she and Tifa were getting things for a midnight feast, as Leah was asleep, and Perry was at Doof's, so they wouldn't get into trouble, but Kero and Yumi followed them into the kitchen.

They got cookies and other stuff, along with soda, but were running to Kai and Tifa's room, but going into the pop up tent.

"Whatcha you think is happening, at your place?" Kai asked them.

"We don't know, guys." Ami said.

Perry shook his head, after getting training pants on Platyborg, as Doof had told him, that at three years old, Platyborg had accidents when he'd put him through potty training, but the teal furred male then saw AJ enter in a purple night dress, but smiled innocently at Platyborg, hugging him.

"i don't like these pants, Daddy!" he told Doof annoyed.

AJ laughed at him, as the three year old cybernetic male had his arms across his chest, and pouting, but unaware that AJ was wearing them under her nightdress, as he understood.

"You guys should go to bed, okay?

You guys need your energy, okay?

Also tomorrow, we're gonna see about school, for you guys." Doof told them.

AJ smiled, as she saw Platyborg protesting he wasn't tired, and flying around the place, as AJ was worried.

"We can handle him, honey." Doof told her.

She hoped so, going to bed, as Doof had put bunk beds in Platyborg's room, but AJ was sleeping in the bottom bunk, but Platyborg slept at the top, if Doof and Perry could ever get him to go to bed.

She yawned, as her eyes closed in sleep, but a few hours later, Doof walked in, carrying a sleepy Platyborg, but tucked him into bed, but kissed his and AJ's heads but turned on the nightlights before leaving the room.

Perry was yawning, as he and Doof were curling up on the couch, but fell asleep.

Annie had heard the chaos from the kitchen.
