The cosmic trio of water gun heroes sweeps away the scorching summer heat!

On a sweltering summer day when even cats feel the heat, three kids start playing with water guns. Instantly transformed into a tomato, a cloud, and a yellow rabbit, they giggle and run through the alleyways, completely engrossed in their water gun fun.

In this fantasy world, the children grab their water guns and march off to battle the heat. They become heroes saving the world from all the creatures wailing about the scorching heat.

Eventually, they fight the sun itself, blazing with heat. The children blast the sun with their water guns, freezing it solid. The warriors who fought the sun, the Three Musketeers of Water Guns, return to reality after playing with their water guns to their hearts’ content. The children, filled with fun, excitement, and joy, shout: “I love summer so much because I can play with water guns!”
