Jumbo Ray

Jumbo Rays are a type of Manta that first appear in New Super Mario Bros. Wii. These rays are green and wear a pair of swim goggles. They have the ability to leap and fly through the sky, so Mario and company can stand on them as platforms until they disappear into the fog. Their appearance and manner are similar to those of Dolphins. Despite being Mantas, they lack the usual pair of lobes around their mouths.

New Super Mario Bros. Wii
Jumbo Rays appear only in World 5-5 of New Super Mario Bros. Wii. Here, Mario and company must use them to traverse the level. Jumbo Rays make a whistling noise when the player jumps on them similar to when the player jumps on a Para-Beetle. However, the Jumbo Rays' sound does not go up the music scale as the Para-Beetle does. Jumbo Rays are not enemies and cannot hurt Mario.
