Ads keep the MarioWiki independent and free :)
The first area has lava that rises at regular intervals, which the player needs to avoid falling into as they climb up the stage. The player first has to cross a falling bridge and then climb up ropes to reach a group of platforms with Katakata Kaen Heihōs on them. To the right is a Springboard that the player can use to reach a ladder. Next is a moving platform that the player needs to crouch on to move under the spiked platform above, and then the player needs to jump onto a hopping Ninji to reach ropes that lead to a platform with the Key. Carrying the Key across two more jumping Ninjis will allow the player to reach the locked door.
In the second area, has to first cross a red bridge with a Lava Bubble jumping up in the center. Next are some more platforms with Lava Bubbles jumping up between them, followed by a ladder, a moving platform, and a rope the player needs to use to reach a blue Color Switch. With the blue Color Switch active, the player can reach a 1-Up Mushroom on the left. Progressing to the right, there is a Hammer the player can use to defeat some Fires, followed by the Mini Mario immediately after.
