Layout
After the land the player starts on is a tall tree platform with a Coin. Next is a scale lift that the player needs to use in order to reach the next platform with Coins and a Koopa Troopa. Afterward is a group of broken up platforms with Koopa Troopas and a Blooper flying above. Next is a horizontally moving lift, followed by a platform, and then another scale with a Blooper next to it. The scale can be used to reach a high platform, but if the player falls to a platform below, they can get back up using some floating blocks as a platform. Over the next platform with a Koopa Troopa is the only ? Block in the level containing a power-up. After some more platforms, another horizontally moving lift, and another scale is the Goal Pole.
