Snake Block

Snake Blocks are Blocks first found in Super Mario World, and reappear in New Super Mario Bros. In both games, they are a set of blocks that start out as a normal platform that begins to move when stepped on by Mario or Luigi. They resemble normal Used Blocks in Super Mario World, but are bright green in New Super Mario Bros. Snake Blocks track across the screen, turning left, right up or down as they follow a pre-determined course over obstacles such as a wide pool of lava, a bed of spikes, or a bottomless pit. Mario must continue to move when on these blocks or they will slide out from under his feet and he will fall to his doom.

The Snake Blocks reappear in Super Mario Galaxy 2 in the Boo Moon Galaxy, Bowser's Lava Lair, and Bowser's Galaxy Generator. Here, they are colored pink. In this game, they make their first 3-D appearance, though they are used in the same way. It is first shown here that they are four blocks wide, instead of only one as shown in its previous appearances in 2-D sidescrolling games. A similar Snake Block called the Ice Snake Block appears in New Super Mario Bros. Wii.
