Ice Snake Block
From the Super Mario Wiki, the Mario encyclopedia
Ice Snake Blocks are a type of Snake Block in New Super Mario Bros. Wii. They appear in World 3- and function identically to normal Snake Blocks, aside from being slippery. Throughout the entirety of the level, they move over bottomless pits. The Penguin Suit, however, allows the player to move freely on the platform without slipping. Only two are found in the level: the first one that leads to the checkpoint, and the second one that leads to Lemmy Koopa.
Ice Snake Blocks can be emulated in Super Mario Maker 2 by placing a Snake Block in the nighttime snow course theme. Additionally, Fast Snake Blocks bear a resemblance to the Ice Snake Block.
