It was a typical day at Maple Elementary School, and the students were buzzing with excitement. The annual bake sale was just around the corner, and everyone was busy preparing their favorite treats to sell. Lily, a curious and creative fourth-grader, couldn't wait to showcase her homemade cupcakes.

As Lily carefully arranged her delectable cupcakes on the table, she noticed something strange. One by one, the cupcakes began disappearing! Lily's eyes widened as she watched the sweets vanish before her very eyes. She knew she had to get to the bottom of this mystery.

Lily decided to investigate the disappearance. She started by questioning her classmates, but no one seemed to have any clues. Just as Lily was about to give up, she spotted a small crumb on the floor. Following the trail of crumbs, she made her way to the janitor's closet, where she discovered the culprit - a hungry hamster!

Lily couldn't help but giggle at the unexpected culprit. She carefully escorted the hamster out of the closet and back to its rightful home. With the mystery solved, Lily returned to her bake sale table, ready to sell the remaining cupcakes. The bake sale was a huge success, and Lily's cupcakes were the talk of the school.
