Super Mario 64 - Stars 4-6 in Jolly Roger Bay Video Walkthrough
Star 4 - Swim down to the ocean floor where there are clams holding red coins. Collect the coins then jump onto the dock and talk to the red Bob-omb. He will open the cannon for you. Climb the nearest peak for another red coin. Make your way to the ship to get the last three coins and star 4.
Star 5 - Use the cannon to blast Mario to the left-most stone pillar. Grab onto it high enough that you can drop down to the secret platform to get star 5.
Star 6 - Swim back to the area where the eel is. Swim down toward the rising bubbles and get beneath star 6 before entering the bubble stream.
