“Why was this hanging out of Ethan’s pocket?” Molly asked.
I picked it up and rolled it around in my hand. It had at least a dozen red buttons on the front but no words. No words anywhere on it.
I pushed the top button. Then I gasped as Slappy began to move. He raised his head and laughed.

I pushed the same button. Slappy raised his head and laughed again.
“What’s up with this?” I cried.
I aimed the clicker at Slappy and pushed another button.

“He must be some kind of electronics genius,” Molly said. “The dummy has a computer chip, right? Ethan recorded all those things it said. He deliberately did it all to scare you.”
