Episode Summary
Phineas and Ferb are in the process of building something huge. The biggest yo-yo ever! Mario observes the blueprint for it, and he thinks it's going to take more help than just his Mushroom Kingdom crew. Buford really thinks if they can make giant ant farms, tires swings, and forts, they're probably able to do this. Phineas explains that it's more complicated then he thinks. Baljeet does math for Buford, but Buford falls asleep three seconds into the equation. In his sleep, he wonders where Perry is. Perry enters into his lair through a fireplace and receives his mission. He is needing to team up with Pinky the Chihuahua, because his nemesis Poofenplotz is up to no good. He tells him not to worry about Doofenshmirtz and to go stop Poofenplotz. Meanwhile, Doofenshmirtz is walking in town when he sees the yo-yo in the Flynn's backyard.
