Escape from Phineas Tower

When Phineas and Ferb are inspired by an antique escape chamber that 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 Roger's meeting with a visiting dignitary from England.
