Flying in behind the buildings, dropping from a parachute from his latest adventure foiling Doofenshmirtz, Perry fell to the ground, quickly hid the parachute and then hid away the hat, god only knows where under his fur. It'd been a long time since he'd gotten to hear Phineas' typical response for when Perry get back from these missions, usually with impeccable timing and he was actually looking forward to it a good deal. That and finding the rest of the ninja class so he could freak them out a little with his disappearing tricks. He'd missed April's Fools Day, but only in date, not in spirit. Bother at will! He's looking to test his skills.
