From the author of Stick Dog comes the first book in a highly illustrated early chapter book series about three best friends whose plans, missions, and schemes are sure to shake up their school. 

Molly gets things stuck in her head sometimes. When she sees a jar of candy on Principal Shelton's desk, she absolutely needs to know how many candies are in that jar!

Luckily, her two best friends, Simon and Rosie, are ready to help her find the answer--even if it means detention for all of them!
