Sansakuoki

Life in the deserts grew increasingly hard for the lumbering ketters. Available water sources began to get increasingly scarce as their populations grew, so the southern population split from the rest and moved farther south in search of water, eventually moving to the rainforest. This gave rise to the sansakuoki. Being in the much more mild environment of the rainforest, their bodies went through radical changes. Since water is in constant supply, they do not need to move as much. They have shrunken their water collecting organs, which allows them to walk much faster. Because their legs are no longer fused together, they are able to move at an increased speed of 1.3 km/h. The sansakuoki, when they reach maturity, stop moving almost entirely during the day to conserve energy. They rely almost entirely on photosynthesis to sustain themselves, and have increased the ratio of photosynthesizing cell to 1 for every 2 skin cells. Their skin is just as tough as their ancestor's to protect them from predators. For further protection, the sansakuoki eat forest demonshrooms for nutrients to collect its poison, which it secretes out of its skin, completely protecting them from predators. They now collect water through a basin above their breathing tubes. To prevent them from drowning, a flap formed that separates their breathing tubes from the basin. They young, compared to the adults, are a different story. When they are done developing from the zygote orbs, they look like a green version of their distant relative, the mini-flower ketter. They feed on the berries of beribarbos until they are near adulthood. When they grow large enough, they form giant forests of moving trees.
