The Green Lady is a type of battleship which was used in an old war. The replica model features a brown hull made from planks of wood, with three gun ports on either side. The top half of the ship is mostly mossy-green with an anchor attached, and text reading "The Green Lady" painted in fancy letters on the ship's side. The ship also features an emerald-green figure head in the shape of a frog-mermaid at the front. The two sails of the ship each feature an illustration of a frog's foot.
