[After Candace busts the boys]

[at Doofies place]
A small ghost came through the wall. "YO DOOF! I'M BACK!" she said. She was an old pet of his who died five years before. Her name was Kat. Kat often came for a visit, but when she wasn't, she was floating around, lonely and bored.

The দিন Kat died was a sad day. She was fifteen, but in Lightopian years- which was her type of alien- she was 103. She died from cancer. She had been suffering from it for a long time. The veterinarian ব্যক্ত she was too old to survive this, and she shouldn't suffer anymore, but Doofenshmirtz didn't want her to put Kat down yet. Neither of them were ready. Then, one day, she was found in a closet, motionless, not breathing, dead. Why was she in the closet? Well, Kat always acted like a child- one with a rare hair disorder. One day, he heard a familiar, child's voice. "I'm back." it said. He turned around, and saw a clearish Kat with a ghost tail. She looked like a child again!

"DADADADA! SUPEREVILKAT!" she yelled. "Kat! Shouldn't আপনি be over in Switzerland?" Doofenshmirtz, now 70, asked. "FYI, they don't allow dead things on the plane!" Kat responded, "I HATE being a ghost! No DS, Wii, PS2- NOTHING!" Kat wished she was alive. Just then, everything changed. Doofenshmirtz didn't rule Danville anymore! Kat noticed him glare at her. "Woah, uhh gotta go!" she said, but only crashed into the wall. She was alive again!
