A/N

This idea popped into my head eariler this afternoon while listening to Phineas and Ferb music in the car but in this, Perry has a brother that hatched from the egg his mother had given him when he went to New Zealand if you've read Missing His Best Friend, you'll understand.

But in this, his brother is visually impaired but Perry and Doof decide to raise him along with Tara but I hope you enjoy this and I'll still work on my other ones.

It was the middle of Summer and at DEI, Doof along with Perry and Tara were getting ready to go to the beach because it was a hot day but Perry went to the incubator where an egg was resting but it was a platypus egg but Perry's mother had given it to him when he'd visited New Zealand and it had one of his siblings inside it but knew it was going to hatch soon but he saw a small crack on it and was excited and decided to wait until they came back from the beach before telling Doof and Tara about it but smiled putting sun screen on him but left the vuilding.

Doof wondered why Perry was so late in getting into the car but he didn't want to tell them as Tara saw a smile on her uncle's face but wondered what was going on.

"It's a secret Tara." was all he said to her.

She hoped that he'd tell her but wondered if it was to do with the egg in the incubator as Perry nodded in reply.

"It's a secret Tara." he said to her.

Later at DEI, Doof was surprised hearing crying but Perry gasped along with him and Tara running to the incubator and seeing an infant platypus in there with turquise fur but Perry smiled as he held it in his arms.

"It hatched from the egg my mother gave me when I was in New Zealand.

I think it's one of my siblings.

Doof I need you to examine it." he said to him.

Doof then followed him to the lab and hooked the platypus infant to machines but Perry saw it whimper as he rubbed it's turquise furred back as it whimpered but they used music to calm it down.

"Where's Tara?" he asked.

"Playing with Jerry.

I know it's going to be a long night." he said.

He then left to take care of Tara but saw she was quiet but knew it was because she was worried about the sibling knowing an new baby took attention away from the first child but sighed seeing Tara watch TV while he odered dinner.

Later Perry saw that Doof had the results from the machine but was shocked reading that his sibling was visually impaired but could go blind when he was an adult but it didn't matter as they would love him no matter what along with Tara.

"I have an idea for his name.

Let's name him Juan." he said as Doof smiled.

He saw the infant in his arms asleep...
