When Mom tells Candace she wants to spend the day with her, Candace spends the entire time with her in the backyard so that she can bust her brothers. Unfortunately, Phineas and Ferb's grand plan for the day only entail watching the grass grow after getting zapped by Dr. Doofenshmirtz's Dull-and-Boring-inator earlier that day. Meanwhile, Agent P partners up with Dr. Doofenshmirtz to fix the now destroyed Dull-and-Boring-inator into a Dynamic-inator in order to fix Phineas and Ferb.

Baljeet: "Actually, that would be..."
"C'mon guys! Get CREATIVE!"
"I KNOW WHAT WE SHOULD HAVE DONE TODAY!"
