One day, in the 3rd dimension, at Phineas and Ferb's house, Phineas and the gang saw weird-looking creatures flying around.
Adam: Uhh, Phineas.
Phineas: What Adam?
Adam: What are those up there?
Phineas: A spider-monkey apocolypse.
Adam: Oh, okay.
Adam: A SPIDER-MONKEY APOCOLYPSE?!!?
Phineas: Everybody, take cover!
Isabella: It looks like now they are squirting a poisones disese.
Adam: What is it called?
Isabella: The internet doesn't say.
- spider-monkeys go twards Gretchen*
Adam: Gretchen! Look out!
- poison hits Gretchen and sends her flying over Phineas' house*
Gretchen: *is nocked out*
Adam: Gretchen! Are you okay?!
Gretchen: *doesn't respond, stays nocked out*
A Few Hours Later[]
Adam: *wispers* Please not be dead, please not be dead.
Isabella: She's recovering!
Gretchen: *recovers* Adam? Isabella? Is that you?
Adam: *does ultra huge, funny smile*
Dr. Fletcher: It apears that she has a very bad disese.
Phineas: Dad, I didn't know you were a doctor!
Dr. Fletcher: So, what happens is that the poison gives the body an infection where the person slowly morphs into a spider-monkey-human!
Adam: IS THERE A CURE FOR THIS?!?!
Dr. Fletcher: Internet doesn't say.
Phineas: I guess we have to find out on our own before it's too late!
Everybody: *stares at Phineas with a silence*
Phineas: Okay, so, what?
Adam: Nothing.
- crowd laughing in backround*
Buford: How did we get here again?
A Few Moments Back[]
Candace: Hold on to something, it's going to be a bumpy ride.
- active music plays in backround*
Everybody: *has searious looks on their faces, exsept Gretchen*
Gretchen: * still nocked out*
Back To The Present[]
Phineas: I've found a cure!
Everybody: What?
Phineas: It is to get all types of liquid medicines and combine them!
Adam: Okay.
Isabella: Careful Katie!
Katie: *serves Gretchen the mixed up medicine*
Gretchen: *spider-monkey-human transformation quickly reverses*
Adam: Isn't it nice to be back to normal, Gretchen.
Gretchen: *stares at Adam and not responding*
