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. Their Chinese and Japanese names suggest that all of them are male.

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 a noise is heard 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, and one of the first mods of the game revealed that, unlike the latter, the former do not whistle when jumped on with Yoshi. Additionally, they are not enemies and cannot hurt Mario.
