Nimbus has so much fun being Kelp's friend! Their days are filled with games, sunshine, and a whole lot of rainbows. Only, Nimbus can't stay sunny all the time; in fact, some days she's downright cloudy.

Nimbus hides her cloud from Kelp and tries to make it go away, only nothing works! Not ignoring the cloud, not running from the cloud, and not bottling up the cloud. It just grows and grows.

And when Nimbus's cloud turns into a storm, there's no way to keep it from others anymore. But maybe getting to know her cloud could make it a little less scary...and maybe friends like Kelp are there to share the weather together.
