The Otyugh is typically depicted with three legs, three tentacles, and an asymmetric body layout.
While many have asked questions about the Otyugh like the number of melee attacks or the grapple, nobody has asked about how movement itself works. The 5E Monster Manual lists a speed in the stat-block, so it must move somehow.
Given its unusual body structure, how does the Otyugh walk – or move, if not by walking?
