Chamoss

Chamoss, also known as chaos moss, is a type of predatory moss. The mainly grow/live on the ground amongst other mosses; chamoss looks virtually the same alongside other dark mosses. But when prey step upon it (for example, a human), large arm-like strands of moss come out from it and wrap it's "arms" around it, then pulls it into the ground, into its digestive system, and so on. Though it doesn't need prey to feed on, it greatly helps it grow and take over more area.
