Calignous Cove is the third stage of Super Mario 64 The Green Stars and is the first water level of the game. It is reached by jumping through a painting in the large house in the first overworld. This basin is composed of many tunnels with almost no room to breath, and requires long amounts of time underwater to reach stars. There are many different colors of Coral that appear, ranging from red to yellow to green. In addition to the coral, there are also many clams, though they do not contain any items.
