Here's more and Platyborg's a little hyper, as Doofy gave him ice cream but will calm him down.

But Platyborg's getting under Perry's fur as he's thinking of him while at work.

Perry sighed as he knew he had to go now to the O.W.C.A before Monogram found out about Platyborg being an infant and would probably send him away from him, but he could hear Platyborg crying, which was making his heart ache, but would try and make him happy when he returned in the morning.

Doof then gave the infant some ice cream, to cheer him up, but Brooke wasn't sure it was a great idea to give Platyborg ice cream as it was coffee ice cream but the turquise furred infant was quiet and happy.

"Brookie, he's a baby!

What's the worst that could happen?" Doof told her.

Brooke sighed, knowing Platyborg would be hyper from the ice cream but he was crawling around the room but Doof thought it was cute.

"Come on buddy, let's go take a bath." Doof told him.

Platyborg then wiggled out of Doof's arms, as he was hyper but Brooke caught him as she started humming a lullaby she'd made up a while ago.

Platyborg then began to calm down, as she handed him back to Doof.

"Thanks, Brookie.

I know Perry's probably missing him like crazy.

He sent me about a dozen messages." he said.

"Of course he does, Doofy.

He likes being Platyborg's father." she replied.

He then hoped that Perry was okay.

Perry noticed it was six in the morning, but was missing Platyborg was doing okay but hoped none of the other agents knew but had heard Peter mentioning about Platyborg, making him mad.

He then realised he could go home, but went to Doof's place, entering quietly seeing Platyborg asleep as he lay on the sofa beside his adopted son.

He couldn't wait for the next few years as he fell asleep.

Doof walked in, wearing his usual clothes but smiled, seeing Perry was back and sleeping soundly besides Platyborg but hoped he was okay.

He had a feeling that Monogram might find out what happened but he'd take care of that.

Perry woke up later, hearing Platyborg grouchy and sneezing, making him worry.

He tried placing a paw on the infant's forehead but Platyborg was resisting him, making him scared.

"I just want to check your temperature.

Please?

I think you're sick and I don't want you to get worse." he said.

Platyborg then let him, as Perry was nervous but picked him up, going to find Doof but saw him and Brooke having breakfast, but he saw a worried look on Perry's face.

He then turned the translator on.

"He's sick, guys.

I need your help." he told them.

"Awwwwwww somebody isn't doing so good, huh?

Let's see what's wrong." he said to Platyborg.

Perry then followed him to the lab along with Brooke, as they were in the lab as Doof was conducting tests on Platyborg to see what was making him sick.

"He has an nasty cold, guys." Doof told them.

Perry then felt relueved, but was feeling sad hearing his little guy was ill but saw Platyborg whimper as Doof was getting a flu shot ready for him.

"It's okay, little guy.

This shot will help you out." he assured him.

Perry then squeezed his paw gently, as the needle was going in but heard him crying as the needle came out but placing a band-aid on his paw.

"You were so brave, Platyborg.

I know you'll feel better soon.

Daddy's gonna help you out." he told him gently.

Brooke thought it was cute but realised she had to go to school, as she grabbed her book bag and left but Doof was going to Phineas and Ferb's along with Perry but taking Platyborg with them.

He had a feeling they could help Platyborg.

"Hey, Perry.

What's wrong with Platyborg?

He doesn't look too good." Phineas asked.

"No, No he doesn't Phineas.

He's got the cold pretty bad." Perry replied.

Phineas felt bad for the infant platypus in Doof's arms, but smiled.

"I know what we're gonna do today!" Phineas told them.

Perry smiled, hearing Phineas say that, as he was listening to the red head's idea about making a special medicine for Platyborg to make him feel better but Doof was helping them.

Perry heard crying and coughing from Platyborg, as he picked him up.

"It'll be okay, little one.

Uncle Phineas and Uncle Ferb are trying to help.

But Daddy's here.

I wish that the cold didn't infect you." he said gently.

Phineas smiled, hearing that knowing Perry cared about Platyborg but he hoped that they could get rid of that cold.

Doof then was using blood samples to help.

But he was willing to help his frenemy.

Poor little guy, as it sucks being ill.

Maybe Phineas and Ferb will help him feel better.

He then saw the boys finish making the medicine to help Platyborg, but were getting lunch as Doof was helping them but Perry was sitting under the tree, with Platyborg in his arms.

"Don't worry, Platyborg.

I got medicine for you." he told him.

Platyborg sneezed but he was being cute.

Doof was sitting under the tree in the backyard beside Perry, watching Platyborg sleep as they were eating lunch but Phineas and Ferb returned carrying lunch for themselves and Perry but saw him yawning, as he was tired from taking care of Platyborg but they thought it was cute.

"We should let him sleep, Doofy.

He looks really tired.

Let's try the medicine out on Platyborg." he told them.

Doof nodded, taking Platyborg in his arms as Phineas opened the bottle, pouring some into a spoon, putting it in Platyborg's bill.

"Good boy.

That should help you." Phineas told him.

Doof smiled, taking Platyborg from him, seeing Perry wake up, but looked a little tired, but eating was bringing his energy back.

He hoped Platyborg would be okay...
