Layout

The first part of the level consists of dodging Flurries while sliding on icy surfaces and jumping over pits. At the far right there is a plant that turns into a Rocket when pulled up, which takes the player to the next part of the level. World 4-1 is notable for being the only level in the entire game without a boss, instead it has a long area filled with many enemies, with the boss music playing in the background. The Crystal Ball is lying unguarded on the ground at the end.
