The bubbles one always works. When my sisters get mad at me I simply growl the word bubbles and they have to look away because they're laughing and they don't want me to know. I love making them mad at me for making them laugh.
Love these enormous coloring posters, chock full of fun, detailed drawings that kids—and adults—will be extra excited to explore and fill in. Hang it on a wall, or roll it over a floor, and spend hours coloring.
