Super Mario 64/Jolly Roger Bay

Jolly Roger Bay is Course 3 in Super Mario 64 DS. 3 stars are required to access it. To get there, go to the room to the bootom right of the first floor, and enter the painting.

Star 1: Plunder in the Sunken Ship
To get this star, you will need to reach the ship in the bottom of the water. Swim down to where the eel is. Get close, then wait for it to get out of the opening. Go in, and you will find a treasure chest. Open it to drain the water from the room. Then, make your way up the platforms to the yellow ? block. Inside it is the star.

Star 2: Can the Eel Come Out and Play?
Make your way to the area where the ships was, then look for the eel. Get close to make it come out. Swim after it to touch the star and make it fly off the eel's tail. Then swim over to the star to get it.

Star 3: Treasure in the Ocean Cave
Swim to the place were you first saw the eel. Go down to the very bottom and on the side you will see a cave opening surrounded by coins. Swim through it until you reach the end. Come up into the cave and run to the back (watch out for the falling rock formations). There will be 4 treasure chests. You must run to them in a certain order (if you don't you'll get shocked). The order is the back chest, the left chest, the right chest, and the front chest. The star will appear.

Star 4: Blast to the stone pillar
Swim to the red bomb-omb and talk with him. he will open up a cannon for you. Swim to the cannon and jump in. Aim yourself at one of the three poles in front of you. When you get on one, climb up to the top, have your back facing the ledge (with the star on it), and jump. You will fall on the platform.

Star 5: Red Coins on the Ship Afloat

 * Coins 1, 2 and 3: Swim under the water. If you look down you will see 4 shells. Swim by each one to open them. 3 of the 4 shells have coins.
 * Coin 4: Swim to the place were the eel is at. At the bottom is another shell. Open it and it has a red coin.
 * Coin 5: Swim up to were the bomb-omb is. Instead of jumping on his platform, jump on the one on the left. Jump across the separated platforms to reach the ship. On the bow is a red coin.
 * Coins 6 and 7: Run up to the other end of the ship and jump on the platform. There are two red coins there.
 * Coin 8: Swim back to the cannon. Jump in, and aim yourself at the pole in front of the bomb-omb's platform. Climb up the pole and you have the last coin. The star will appear. The star is on the ship where coins 6 and 7 were.
