Eek! Halloween! Board Book by Sandra Boynton

There's a big round moon in a dark, dark sky. The chickens are nervous. Do you know why?
Strange things are happening. One chicken saw a pumpkin with flickering eyes, another spied a mouse of enormous size. They all saw a wizard and a witch, and a spooky robot. “WHAT’S GOING ON HERE? WHAT DOES IT MEAN? / Relax, silly chickens! It’s HALLOWEEN!”
