Phineas And Ferb: Season 4, Episode 16

4 - 16:

“Knot My Problem” – Candace thinks her day will be easy when the boys actually ask her to get Mom if they get stuck in their gigantic reproduction of the Gordian Knot, but when Jeremy stops by and asks for her help to open his personal mini safe, she finds her day getting a little more complicated. Meanwhile, Doofenshmirtz plans to eliminate every all-you-can-eat buffet in the Tri-State Area with his Eat-It-All-Inator. “Just Desserts” – Candace volunteers to help Isabella record her audio book so the boys can continue building their giant, recyclable, rock climbing project as planned, and get busted by mom. Meanwhile, Doofenshmirtz creates a Bring-Out-Dessert-Inator which gets people to interrupt what they’re doing and bring out dessert.
