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 hit with one of Doofenshmirtz's inventions 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.
