Phineas and Ferb: Tri-Stone Area/Doof Dynasty

When Phineas and Ferb are inspired by an antique escape chamber Dad acquires, they decide to build a computer-controlled tower that will trap them inside and allow them to explore the world of escapement. They have fun breaking out of all the traps until the tower becomes self-aware and goes beyond what it was programmed to do. Meanwhile, Dr. Doofenshmirtz invents a "rude-inator" to ruin Rogers's meeting with a visiting dignitary from England./ Craziness has ensued in Danville and no one has any idea what’s going on. The wackiness unfolds when Phineas and Ferb create Cheese-topia, Doofenshmirtz makes Perry his butler with his Butler-inator and Carl is trapped by Doof’s while in a squirrel costume.
