That's the Spirit

Let's go bust us some ghosts!

It's Halloween night and the kids encounter a strange boy named Russel and his father who are convinced their house is haunted. Meanwhile, Dr. Doofenshmirtz's disdain for grass causes him to invent a "mind-transfer-inator" enabling him to merge minds with a cow and destroy all the grass in the Tri-State Area. Unfortunately, his plan backfires and he transforms into a scary "were-cow" that wreaks havoc any time there is a full moon. It's now up to Agent P to stop him and save Danville.

Episode Summary
While trick-or-treating, Phineas and Ferb meet up with their friends; Phineas being a vampire, Ferb being Frankenstein, Baljeet being a daisy, Buford being a pirate, and Isabella being a fairy princess. While walking, they come across a house that they have never seen before. As they approach it, they meet a boy hiding in a bush named Rustle. Rustle says that hiding in the leaves makes him warm and secure, relatively speaking. Baljeet asks why he does not go inside the house and he confirms that it's haunted. Phineas decides that they should help Rustle by busting the ghosts, and Rustle reluctantly follows.
