World 5-1 (New Super Mario Bros.)

World 5-1 is the first level of World 5 in New Super Mario Bros. It is the first and the only level to include Snow Spikes.

Layout
The level begins with a Snow Spike on a platform directly above Mario's head and four Goombas in front of him. Then, after jumping the pit beyond the Goombas, there are some trees that have snow on them. The second tree will drop the snow, stopping Mario cold. Following those are a few Question Blocks and an indentation containing deep snow. This will cause Mario to sink in a little and reduce his jump height. Soon after that are a few more trees, Goombas, and another Snow Spike. After defeating the Snow Spike, Mario can get the first Star Coin. Then there is a pit of deep snow and another Snow Spike. Defeating the Snow Spike results in the appearance of the checkpoint flag, and leaping the pit brings Mario to the second star coin. Soon after passing the second star coin is the third, protected by a Snow Spike. Soon, after avoiding the rest of the Snow Spikes, Goombas, and harmful snow, Mario reaches the Goal Pole.
