Quick Roper

A mutated type of roper which suddenly appeared one day in the forest. It usually keeps its tentacles inside its shell, and stays completely still. It also has an extremely pungent, rotting odor, so it doesn't look like a living creature in the slightest. But the moment humans or animals goes near it, it lashes out with its tentacles to try and snag its prey. Until recent, these dangerous ropers weren't known, and details of when and how they appeared is unknown.
