The Other 50% Reef is a coral reef in the Southeastern Sea. It earns its name from 50% Luke, a pirate that lost half of his body to the reef. The reef is close to Luke's Reef, a similar reef that Luke discovered when he fell overboard on his captain's ship, The Inebriated. Like Luke's reef, The Other 50% Reef consists almost entirely of a species of extremely spiky coral. However, it is considerably taller, nearly reaching a ship's hull.
