While doing another one of Phineas and Ferb's activities, the squad, along with Phineas and Ferb end up crashing into the building of Heinz Doofenshmirtz, the arch enemy of Perry the Platypus. Unaware that Doofenshmirtz is an evil doer, Phineas, Ferb and the squad help him create his latest inator; a machine that allows inter dimensional travel. Once completed, the team ends up in a parallel dimension to the Summer Realm, ruled by a more evil version of Doofenshmirtz.
