Layout
The level is an ice-themed level, which primarily features Bumpties and short jumps, as well as Donut Blocks and Stretch Blocks in some areas. One point in the level is an auto-scrolling area in which the screen begins to move back and forth, moving faster each time and revealing more of the area until a Warp Pipe becomes visible, at which point the screen will stop scrolling.
