Once upon a time there was a boy. Everyone thought he was weird because of his big mouth. But little did this group of people know: He actually was Perry the Platypus on an undercover Mission. His old enemy Heinz Doofenshmirtz had been replaced by the new teacher Ms. Prasselmann. Her gooey goo vagina powers were so powerful that she just had to put her index finger and thumb together to paralize you in disgust.
Meanwhile Phineas and Ferb were working on a tremendous wepon to defeat her. However Perry didn't want them to defeat her just yet. First he had to find out where his enemy had disappeared to. Heinz was not only his enemy but also his true everlasting love. They were having a secret realationship. That's why Doofenshmirtz divorced his wife. He didn't want to keep hurting her by not returning her feelings anymore.
The ex wife and Ms. Prasselmann knew eachother well. The second wanted more than friendship. But she was the worst lesbian in history. "Ghettofightclublesbian" she got called by everyone.
The ex wife was still obsessed with Heinz and was trying to get back together with him. She was too caught up in her own feelings to realize those of Ms. Prasselmann for her.
This is the reason behind Heinzes kidnapping: Ms. Prasselmann kidnapped him so his ex wife wouldn't think about him for a while. She wanted a second chance to show the ex wife how much she loved her.
In the mean time Phineas and Ferb finished the ultimate weapon and were ready to fight only waiting on Perrys commando. But Perry first had to find Heinz. His plan was to confess to him after saving him.
He got a message from Major Monagramm, who just located Heinz Doofenshmirtz in Ms. Prasselmanns "Ghettofightclublesbian"-Basement, her secret laboratory.
Perry hurried to her house and was very surprised at the sight of it. He could have imagined anything, but not a house completly consisting of Jello. His distorted reflection stared back at him from the green gooey goo walls of the montrosity the called the "Ghettofightclublesbian"-House. In his eyes he saw the fear; fear from loosing to Ms. Prasselmann, but loosing Heinz was his biggest.
He dived into the goo slowly moving forward. At this moment he was really glad he wasn't the boy he pretended to be at school to be near the fake teacher Ms. Prasselmann , but he was a platypus. Perry the Platypus. He could hold his breath long enough so he could find his Heinz.
Afraid of the traps that might be hidden in the gooey jello he swam carefully to the basement. Suddenly the angelic voice of his love crying for help found its way to his ear caressing it with the smooth Doofenshmirtz accent. He swam faster to find Heinz chained u against the wall. Pure relief was in the eyes of both of them after Perry set him free. The urge of telling Perry his feelings grew in Heinz. Was it too early? No. They had spent so much time fighting like an old married couple. Now or never. Perry had saved him and they were reunited for a reason.
"Perry...", he started silently trying to find the words to express all the love he felt,"I will never be happy without you. Please, never leave me. I want you to be mine."
Perrys eyes grew wide and tears started pouring down his soft turquoise cheeks. He couldn't help it. All the feelings he had to hide all these years broke out. "Grrrrrrrrrrrrrrrrrrr❣"
Heinz who always wanted to be the dominant one pulled Perry into a longing and passionate kiss. His evil heart was beating so fast he had to start inventing a Heart-Slow-Down-INATOR™. Still he felt his heart ache when the had to break the kiss to breathe for a second. The stare between them was was intense and promissing, not at all like the boring Edward and Bella stares.
"No you misky bastard!", suddenly the ex wife appeared, screaming like a fury while holding up a gun aimed at Perrys forehead.
At this exact moment Phineas&Ferb™ invaded the basement surrounded by melting jello. Their ultimate weapon of destruction: The gigantic flying Baby head with Lazer-Eyes®, shot down the malicious ex wife at an instant. After her defeat Heinz picked Perry up again wanting to leave as Ms. Prasselmann walked in. "Not. So. Fast!"
Phineas&Ferb™ disappeared again with their gigantic flying Baby head with Lazer-Eyes® and the Perryshmirtz couple was left alone risking their future by facing Ms. Prasselmann.
She stared down at the ex wifes corpse but instead of the expected tears there was something else forming on her face. A smile started creeping onto her lips. The basement was filled with her laughter.
"You two can't just go yet. I have to thank you for killing this terrible woman who went crazy from her endless love for Heinz. She would have never loved me the way I love her. While I held Heinz captive I realized the thing between me and her was nothing but an obsession. My love and heart belongs to this beautiful Lady, Ms. Sippy!"
Another middle-aged woman came out behind her and with her annoyingly cheerful voice said, "This is the so called true love!"
"So, uhm... you'll let us go now?", Heinz asked.
"Yes", Ms. Prasselmann said."You're free to go. I know beeing apart from your soulmate is the worst poison for your heart, but being held chained up with eachother would eat you up from the inside out. I mean I'm evil, but I'm not cruel and heartless."
"Grrrrrrrr :)"
"Sorrehhhy?",Ms. Sippy was a little confused,"I didn't quite understand what you said."
Ms. Prasselmann was quick to answer,"Does it even matter? Love has no language. It's right here", pointing towards her girlfriends chest.
"Let's go and build a Marrige-Inator©", Heinz went down on his knees looking down to his soulmate and took a dimond collar out of his torn lab coat.
"Will you my beloved Platypus do me the honor of accepting my engagement proposal? I even promise not to build as many Inators to do bad things."
Perrys answer was a loving and soft Grrrrrr as he motioned Heinz to put the collar on him. It fit perfectly.
Doofenschmirtz pulled his fiancee in a warm hug not even thinking about loosening his grip on the other for one second.
"I wondahh... huh... is Perryshmirtz going to fuck now even if we're still in here, Prassely?" "If so I'm going to cover your eyes with my gooey goo so we can leave but I'll leave a bottle of my finest organic vegan gooey goo lube for them to enjoy ..."
Perryshmirtz didn't hear them. They were way too lost in their loving space to recognize the disappearence of the women in gooey goo slime. Instead they started to get very comfortable with eachother.
They also didn't notice the ex wife getting up and mumbeling:
"TO BE CONTINUED."
