Variant of Maw-Ray

Mega Unagi[1] are a gigantic version of Unagi that appears only in New Super Mario Bros. Mega Unagi appear in two underwater stages in the game, World 4-3 and World 8-3, the latter in which one chases Mario (or Luigi) throughout the latter half of the stage. Mega Unagi are very dangerous, and they destroy everything they can, such as bricks and ? Blocks. There is no way to defeat a Mega Unagi. However, Mario can go "through" one with a Mega Mushroom or a Starman, by swimming through its back, as Mario will collide with it if he tries to go through its face. However, in World 8-3, when Mario moves alongside its face, the Mega Unagi swims slower and also tries to crouch down on and corner Mario to the top or bottom surface of the screen. As long as the Mega Unagi is positioned at the very top or bottom of the screen, if the player crouches down at the very bottom of the ground or stays at the very top edge of the screen while the Mega Unagi tries to crush Mario with its body, eventually it will swim forward and vanish from the screen, but it will return after approximately one minute. Unlike Cheep-Chomps, Mega Unagi cannot eat Mario and cause him to lose a life instantly; instead, the player takes damage like a regular enemy.

Normal Maw-Rays are larger in most subsequent appearances and thus appear to be closer in size to Mega Unagi.
