Westie rubbed his eyes, barely able to believe he was seeing ghosts. Though it was rather dark. This gave him an idea. He pulled out one of his inventions—Moon-Glasses! They were like sunglasses, except they helped you see at night. As soon as he put them on, Westie looked back inside the dojo.

“That’s no ghost army!” Westie whispered to himself. “Those are ninja!”

The ghosts he thought were floating along the ceiling probably had tails and whiskers, and they were using their claws to crawl across the ceiling so they could avoid walking on the alarmed floor!

“Rider was right,” Westie told himself. “There’s no such thing as ghosts. Those are cat burglars!”

The five ninja cats made it across to the other side. Then one by one, the cats held each other’s legs. They pulled out small mirrors to divert the lasers safely away as they made a ninja ladder. The alarm wouldn’t go off with the mirrors in place. Finally, the bottom cat used his claws to cut a hole in the glass case protecting the scroll, reached inside, and took the scroll.

“This is a major cat-tastrophe!” Westie said. “They are stealing the scroll . . . unless . . . unless . . .” Westie had done terribly in the Bark-Jitsu class. What could he do against ninja thieves?

“I am a brilliant inventor and a detective,” Westie reminded himself. “And now it’s up to me to save the scroll!”
