DISCLAIMER: I DO NOT OWN ANY OF THE CHARACTERS. I DO NOT OWN PHINEAS AND FERB, NOR DO I OWN DEATH NOTE. (If I did, I'd be rich) THIS IS ONLY A FANFICTION.

Author's Note: I got the idea for this from the title of a YouTube video. I also do NOT own that video in any way. This is my first posted fanfiction, and I'll try to post regularly for all my stories, including this one.

It was the average summer day in Danville. It was warm, sunny, and Phineas and Ferb were un the backyard, with Candace staring at them, making sure they weren't going to make any crazy contraption, even though they would regardless of if she was watching them or not.

The two step-brothers were sitting under the shade of the tree. Perry was already missing for the day, and Phineas had already said to Ferb, "Hey, where's Perry?". Like always, there was no answer.

"Hey Ferb," said Phineas, "What are we gonna do today?" Ferb gave a silent shrug in response. Phineas sighed, "We've got no ideas. We should've made plans yesterday… How could this happen? We always have plans ahead of time! What was I thinking? Something would just fall out of the sky?"

Not a moment after he said this, a black notebook randomly fell from the sky. Phineas smiled and looked to Ferb, "Wow! I didn't think that would work." They went over to the notebook when they were interrupted by the opening of their gate.

"Whacha doin'?" asked Isabella.

"We don't really know yet, but we think that it has to do with this book that just fell from the sky," Phineas answered without breaking his smile.

"WAIT! Let me do it!" Isabella began running towards the fallen book, "I'm working on earning my 'picking up strange books that fall from the sky' patch."

The two boys let here get the book. She brought it over to them. The notebook was black and in the top center of the front cover it read, 'death note'.
