When Phineas and Ferb take a time machine twenty years into the future, they meet a grown-up Candace, still determined to get them in trouble, who goes back into the past to stop them, as Perry the platypus continues to battle Dr. Doofensmirtz.

It's all fun and games when Phineas and Ferb create a swimming pool full of gelatin...until Dr. Doofenshmirtz's latest creation brings it to life! Phineas and Ferb have to find a way to stop the giant gelatin monster and save Candace.
