Puff the cloud is distressed because he doesn't know how to rain. Another friendly cloud gives Puff some advice. Puff should go sit in direct sunlight over a pond, and then he will have enough water to rain.
Puff heads over to a nearby pond, directly in the way of the sunlight. The friendly cloud's advice worked! Puff feels the sun direct water droplets into him. Now he's bigger and fluffier.
Puff heads over to his favorite patch of flowers. He readies and steadies himself, and with a big heave, he is able to rain all the fresh pond water all over the flowers. Puff did it!
