Overview
Its seabed is a yellow color. It is where the Gem of Courage is located, which is inside the mouth of a giant reptilian-like fish. It is possibly called the Yellow Reef because of the diversity of the yellow coral reefs surrounding the area. The Ocean Gate between Earth and Domino is located here and according to Serena, the Yellow Reef is home to the Magic Dimension's rarest species of fish.
