Perry the platypus pressed himself against the walls of the Doofenshmritz of Evil incorporated main building. After carefully checking to see if the coast was clear before using his grappling hook to pull himself towards the window. He then kicked down the window as his grappling hook reeled him into the building. He landed on his feet in fighting stance. It was clear that Perry was ready for a duel; his so-called opponent however was not.
"Perry the Platypus, couldn't you have broken through the window a little more quietly?"Heinz Doofenshmritz whined, " You're too early anyway I have not even started to wake up yet let alone made my invention."
Perry saw that Dr. Heinz Doofenshmritz was looking like more of mess than usual. The evil doctor was still in his nightgown and been sweating and shivering at the same time. Perry could tell his nemesis was suffering from a fever.
Meanwhile Phineas and Ferb were working on their 5-D theatre. Then their friend Isabella went up to them.
" Hello Phineas, Whatcha doing?" She happily asked her crush.
"Oh we were working on a 5-D movie theatre." Phineas explained to her "Although it not going as quickly as we would like it to."
" Would you like me and the Fireside girls to help?" Isabella asked." I bet rest of the Fireside girls would love to help it will give them a chance to earn their Contribution to Improvement of Entertainment badges. "
"No we would not like for you to help us." Phineas remarked.
This made Isabella frown.
But then Phineas said, "We would love for you and the Fireside girls to help us. The more the merry right Ferb."
Ferb nodded his head and put his thumbs up in order to show he was in agreement with his stepbrother.
"You would love to have us help," Isabella sighed blushing at the thought of Phineas loving something that had to do with her.
Phineas noticed that she had gotten red around the cheeks but was unaware of the cause.
"Oh my, you're turning red Isabella. You might have fever." He worriedly informed his friend.
He took her temperature with a thermometer. He smiled when he saw that her temperature was regular.
"You must have just had a rash, but don't worry about that as it seemed have cleared up on it's own." Phineas told her.
Isabella thought it was funny that he thought she might be sick when she was really just blushing.
"Oh Silly, I was just blushing." Isabella explained.
Although Phineas did not know why Isabella was blushing he was glad to know she was all right.
"Okay after we go get the rest of the Fireside girls we will resume building." Phineas told Ferb and Isabella
Ferb gave him the thumbs up
Isabella replied, "Sounds like a plan."
