Kelpie (Dungeons & Dragons)
The kelpie appeared in the third edition Fiend Folio (2003).
A kelpie is a mass of animate seaweed that can alter its form to resemble a woman, a hippocampus, or a green horse. It can charm a humanoid into thinking it can rescue the kelpie, which then grapples the victim until it drowns.
