Nature Clan: Spring World, otherwise simply known as Spring World, is a game in the Nature Clan series. It was designed for inclusion on plug'n'plays, and its hardware is based on VT02/Famicom.

Spring World has very similar gameplay to Pindable Crystal Ball, since Nature Clan's goal is to collect an item while avoiding obstacles. Spring World has a larger variety of enemies, and Nature Clan has to collect coins rather than green spheres.

Spring World had a sprite hack called Cool Baby, which was made by Qi Sheng Long.
