Yet, Another Time Traveling Adventure

Chapter I - Heinz's Time Traveling Portal / No More Big Ideas
Isabella, Buford, Baljeet and Andrew walked through the gate to see what Phineas and Ferb were doing. "So, whatcha doin'?" Isabella asked, with a sweet smile on her face. "Well, Ferb and I don't know, yet." Isabella, Buford, Baljeet and Andrew gasp in shock. "Who are you, and what have you done with my neighbors?" Andrew asked. "Andrew, it's still us. We seriously don't know what to do." Phineas said, looking at many blueprints. "Well, maybe you need to be inspired." Andrew suggested. "Hey, where's Perry?" Andrew asked. Just then, while no one was looking, Perry put on a 1940s fedora, and ran to his Secret Lair. "Good morning, Agent P," Major Monogram said. "Doofenshmirtz has been carefully examining blueprints to a Time Machine." Just then, Carl butted in, as he said, "I bet this means he's working on a Time Machine." To which Monogram replied, "You don't have to be so obvious, Carl." Perry ran out of his lair, hopped on his motorcycle, and headed to Doofenshmirtz Evil Incorporated. Meanwhile, back at the Flynn-Fletcher house, Buford, Baljeet, Isabella and Andrew all waited for an idea to pop into Phineas and Ferb's heads. "Just think of something already, Dinnerbell!" Buford shouted. "Well Buford," Phineas said. "We'd think of something, but we don't know what." Everyone was silent for a few seconds, when Buford stated, "This is lame." Meanwhile, at Doofenshmirtz Evil Inc., Perry arrived, as he noticed something wasn't right—there was no trap. "What? Oh, you were expecting a trap, weren't you?" Doofenshmirtz asked. Perry nodded. "Don't blame me, blame the idiot writer for not being able to think of a clever trap."
