Where’s My Perry? continues to expand its physics-based gameplay with not one, but two sets of new levels.

The popular spin-off of Where’s My Water? has just been updated with new Agent P levels and Dr. Doofenshmirtz levels.

In Where’s My Perry?, Perry aka Agent P from Disney’s “Phineas and Ferb” is summoned for a mission briefing at agency headquarters. But on his way there, he gets stuck in his transportation tubes.

As such, Agent P needs your help as he tries to get unstuck in every level of the game. Your own mission, should you choose to accept it, is to free Agent P by channeling water in all its different forms to the tubes’ backup generators.

In the recently updated Where’s My Perry?, 20 brand new levels starring Agent P await you. You can find them inside Mission 7: “The Last Laugh.”

As many new levels are also added to “Doofenshmirtz Evil Incorporated,” the other level pack in Where’s My Perry?.

In “Doofenshmirtz Evil Incorporated,” your mission is to help the “Phineas and Ferb” villain Dr. Doofenshmirtz in creating an evil army. To do that, you have to use black sludge to power the mad scientist’s Minion-inator, which transforms everyday household objects into evil minions.

Compatible with iPhone, iPod touch, and iPad, Where’s My Perry? is available in the App Store for $0.99.

Where’s My Water? is also available in the App Store for the same price.
