Hayden was an adventurous kindergartener who loved solving mysteries. One day, he noticed that all the cookies in the kitchen had mysteriously disappeared! Hayden decided to investigate and find out what happened to his delicious treats.

He began by examining the kitchen for any clues. He noticed some crumbs on the counter and a few pawprints on the floor. "Aha!" Hayden exclaimed. "I think we have a cookie thief on our hands!"

Hayden followed the pawprints and discovered that they led to the family's pet dog, Buddy. "Buddy, did you eat all the cookies?" Hayden asked. Buddy just wagged his tail, looking innocent. Hayden knew he had to dig deeper to solve this mystery.

Suddenly, Hayden heard a strange noise coming from the pantry. He slowly opened the door and found Buddy curled up, fast asleep, surrounded by the missing cookies. "Aha, I've caught you, Buddy!" Hayden said, trying not to laugh.

Hayden's mom came into the kitchen and was surprised to see the scene. "Looks like you've solved the mystery, Hayden!" she said, impressed by her son's detective skills. Hayden felt proud of himself for cracking the case of the disappearing cookies.
