Ice Snake Block

Ice Snake Blocks are a type of Snake Block in New Super Mario Bros. Wii. They appear in World 3's castle. They are very slippery, and Mario, Luigi, Blue Toad and Yellow Toad must not slip off it because there is a bottomless pit under the Ice Snake Block thus causing them to fall and lose a life. The best strategy to guarantee to have a low chance to falling off is to use the Penguin Suit. Only two are found in the stage - the first one that leads to the checkpoint, and the second one that leads to Lemmy Koopa.
