Publisher's Synopsis
This is a summer that is extremely hot, the rainbow rain is belatedly coming, and everything is so dry that it is almost turning into a desert... Where is the rain hiding? Piggy and his friends love to roll and play in wet mud puddles! However, this summer is hotter than usual. Not only that, even though some dark clouds are slowly gathering in the clear sky, it still can't rain. The earth lost its moisture, the rivers gradually dried up, and even the mud quickly turned into coarse sand. The brave little pig volunteered and was ready to set off to find the rain. Along the way, he met various animals, asking and searching for traces of the rain.
