World 6-4 (Super Mario Bros. 3)

World 6-4 is the fourth main level and the fifth level overall in Ice Land from Super Mario Bros. 3.

Layout
The level starts with three Donut Lifts, a small and large Ice Block, and two Rotary Lifts, before coming across a structure made of Ice Blocks with three Goombas and a 1-Up Mushroom inside a Brick Block. After leaving a platform made of large Ice Blocks, there are two lifts, a ? Block with a Super Leaf, and a Magic Note Block that sends the player to a Coin Heaven with many coins. After this, there is a pillar of large Ice Blocks, a Switch Block atop a pillar of Brick Blocks, and two long platforms made of large Ice Blocks. The first one includes short pillars of Ice Blocks topped by Rotary Lifts, one of which atop a row of Brick Blocks, and the second one has three short Ice Block Pillars with Rotary Lifts. A Fire Chomp appears at the second large Ice Block platform, and a second 1-Up Mushroom can be found in a Hidden Block high above the platform. A large Ice Block with another Rotary Lift is at the end of the second platform, which is then followed with the goal.
