Jolly Roger Bay

Jolly Roger Bay is the third course in Super Mario 64 and its remake, Super Mario 64 DS. The entrance to the course is through the ★ door to the far right of the first floor of the Mushroom Castle, and three Power Stars are needed to unlock the door. The course is a large lake with several rocks, platforms, and a ship. It gets its name from "Jolly Roger," a name given to typical pirate flags.

Layout
The player starts on the shore of the lake, which consists of a yellow block to the left and a green block (red in the DS version) to the right. In the DS remake, the shore also contains Goombas and a block containing a Shiny Shell. Over to the right is a platform with a Bob-omb Buddy, who will open the cannon of the level when talked to. A large spire with a Red Coin at the top is located nearby, and going across the platform on the water will lead to a series of platforms and another green/red block. Pressing the Purple Switch will make additional platforms appear, making it easier to cross them all. At the end of these platforms is the raised ship, but only in missions two and onward. The ship provides a platform for the player to reach three of the Red Coins in the level, as well as the location of the Power Star that appears when all the Red Coins are collected.

In the Nintendo 64 version, during the first mission, Plunder in the Sunken Ship, a thin fog covers the area, and the sky is darker than in other missions. The player can enter the ship in the lake through a broken window after luring Unagi the eel out. The inside of the ship is full of water and contains several Treasure Chests and platforms. Opening these chests in the correct order will drain the ship and allow the player to jump up the platforms and collect the Power Star at the top. Strangely, the drained ship's interior remains upright when it should be horizontal, as the ship is presumably floating on the water. After the player collects the first Star, the fog and dark sky effects will bizarrely not return anywhere in the level, even if replaying Plunder in the Sunken Ship.

Above the water, near the start of the level, is a cannon that is needed to reach the Power Star during the mission Blast to the Stone Pillar. Below the cannon underwater are a ring of coins and two clams: The one on the right has a Shiny Shell, and the other has a Red Coin. Past the three stone pillars is a large trench where the ship lies during the first mission. During any other mission, a jet stream is in the ship's place and Unagi moved to a crevice up above. The Ocean Cave is to the west, containing many large rocks that fall on the player if they get too close, Goombas, and a green/red block. At the back of the cave are several Treasure Chests that will provide the third Star when opened in the correct order and, in the DS version, a large fenced-off area containing another Star.

Trivia

 * In the first release of Super Mario 64 in Japan, the entrance to Jolly Roger Bay is a painting of bubbles in a blue frame. In all subsequent releases, including the Japanese Super Mario 64: Shindō Pak Taiō Version rerelease, this is changed to a painting of a sunken ship in a gold frame. Super Mario 64 DS instead uses a retouched version of the original painting in all versions. In Super Mario 3D All-Stars, the revised ship painting is used due to the Shindō Pack rerelease being the basis of the included version of Super Mario 64.
 * Exclusively in the Nintendo 64 version, a hidden ship duplicate that appears only during the mission Plunder in the Sunken Ship is floating above the stage, which cannot be seen through normal means.
