Summary
“Then he glanced up, looking out from the corners of Heinz’s neck and collarbone. He gasped. A shooting star had flown by. It was his chance!
‘I wish for Heinz and I to meet again! I don’t care how, but I want to see him again! I don’t want to forget him! Please!’
He knew it was childish, but his parents would do it too and told him, “If you ever see a wishing star, only make a wish you truly and desperately want. It’s special. So make sure the wish is too.”
His grip along Heinz’s ribs and waist tightened as desperation lit his veins icily and he gasped. He clung desperately, feeling Heinz tighten his hold and mumbling in his sleep. He pressed his nose to the base of Heinz’s neck, hoping he could memorize the scent enough where meeting and being with Heinz wouldn’t be just a daydream and he didn’t want to suddenly open his eyes and see himself in his aunt and uncle’s car. As if Heinz never existed. He fell asleep a while after, still clinging onto the boy he’d have to leave.”

Feet stumbled through the cryptic forests; ragged breathing filled the deafening silence and fear filled the misty air, three figures hurried through the horrid woods as a figure rushed after them, weapon in hand and gleaming in the moonlight.
“PHINEAS HELP!”

Doofenshmirtz grinned, giving Perry a good look at his sharp teeth. ”So, I thought to myself 'Heinz why can you never win? There must be something you're missing...' and realized the answer was a lack of animal instinct. Anyway, do you like it Perry the Platypus? I turned myself half ocelot!”

Summary
“Ah, Agent P! How nice of you to drop in! I take it you're here to find your fellow agent, hm? Well, I'll let you have him!” Rodney hit a button on his remote control, and a metal door slowly slid up behind Perry. He shivered as a deep growl echoed through the space, and he turned to see Heinz's blue eyes glowing eerily in the low light.
“My new nemesis, as you can see, isn't feeling himself anymore... thanks to my Regress-inizor! One blast takes any highly trained OWCA agent and turns them back into a mindless animal!” Perry shivered as Heinz growled again at Rodney's cackling. Even as Perry listened, his eyes never left the ocelot, who had finally emerged from the cell and was now moving towards Perry.
“I can't stand the sight of blood, however, so I'll just leave you two to it!” Rodney declared before flouncing off.

Heinz blinked, looking up from his food. The front door shut, and before Heinz could move the sound of a very familiar tread walked into the kitchen and halted abruptly.
