The park buzzed with activity, the sounds of children’s laughter mixing with the rustling leaves. Leo sat on a bench, watching his niece, Chloe, swing so high she almost touched the sky. A wave of contentment surged through him.

He was surprised, then, by the peculiar drawing Chloe had made. There, amidst the usual scribbles of trees and sunshine, was a form he knew very well: a creature with three eyes and a penchant for singing off-key.

Leo had to ask. "Chloe, what is this creature?" A flush of pure, unadulterated pleasure rose in him.

Chloe stopped her swinging and gave a confident, enthusiastic answer. “That’s Giggle-Puff! He’s always happy to play with me!" Leo could barely keep his excitement in check, a smile threatening to split his face.
