Coach (Super Mario Galaxy)

Coach is a tall black penguin similar to Penguru from the Sea Slide Galaxy. He is a swim instructor from the Beach Bowl Galaxy in Super Mario Galaxy, who gives advice as to the location of one of the Power Stars in that area. He can be found teaching the other penguins how to use a shell to improve their swimming. He may be the same penguin that leads Manta Ray Surfing in the Loopdeloop and Loodeswoop Galaxies, but that is not certain.

Ray Surfing
Ray Surfing is a penguin sport which is similar to our surfing, but on the back of a manta. Ray Surfing is similar to Blooper riding in Super Mario Sunshine, but the player controls ray with the Wii remote, rather than the joy-stick or the D-pad. Mario must ray surf in the Loopdeeloop Galaxy, and the Loopdeeswoop Galaxy to gain one Power Star for each challenge.
