It was a sunny day in the small town of Riverdale when Emily, a curious fourth-grader, stumbled upon a peculiar mystery. As she was walking home from school, she noticed something strange – a bright blue butterfly fluttering inside a girl's nose!

Emily couldn't believe her eyes. She quickly approached the girl, who seemed quite distressed, and asked, "Excuse me, are you alright? There's a butterfly in your nose!" The girl, named Lily, looked up at Emily with tears in her eyes and explained that the butterfly had flown into her nose while she was playing in the park.

Without hesitation, Emily knew she had to help her new friend. The two girls set off to the park, determined to solve the mystery and free the butterfly from Lily's nose. They searched high and low, looking for clues and trying to come up with a plan to safely remove the butterfly.
