Grudge Dolph is a brown ship with a voodoo doll-like figurehead with a giant nail through it. It has five cannons on its front underneath the figurehead (the center of which seems blocked by the nail) and two masts. The front mast has a black sail brandishing the crew's jolly roger, two smaller jolly roger flags on each side, a crow's nest, and a giant candle on top. The back mast has another black sail and jolly roger flag. The ship's helm is on a raised platform, which is decorated with voodoo masks. The ship's cabin is designed to look like a shack with a straw roof, and the ship has five windows on each of its sides.
Grudge Dolph was docked alongside Stay Tune and Victoria Punk on the coast of the Kid Pirates' hideout island as Kid, Apoo, and Hawkins formed their alliance. It is unknown what happened to the ship after Kaido landed on the island and fought the crews.
