Age range 5 to 9 Happiness and kindness can be contagious! Ripple, the new dolphin at the aquarium, is surprised that no one in her new home plays or has any fun at all - all because of a bullying shark named Snark. Ripple teaches her new friends that happiness is a choice, and that we can each make the world a better place because of who we choose to be. They challenge Snark to a staring competition - if they can make Snark smile, everyone gets to play. If not, Snark's no-fun rules will rule. Will Ripple have the effect she hopes for?
