The Manta Ray's Reward

The Manta Ray's Reward is the fifth mission of Dire, Dire Docks in Super Mario 64 and its seventh and final mission in Super Mario 64 DS. Other than the mission number, nothing has changed.

In the first area of the course, there is a Manta Ray circling about halfway down underwater. The Manta Ray drops bubble rings as it swims, and the player needs to go through five of them. If the player misses one, the counter will reset. Once five consecutive bubble rings have been passed through, the Power Star appears above the whirlpool in the center of the area.
