The player first has to move right while dodging lasers, using a Bob-omb as a moving platform if needed. Jumping onto the platform above, the player has to press a Direction Switch and then climb up into the area above. Using the Springboard, the player needs to toss three Bob-ombs onto the conveyor belt above to open the path below on the right. The player then has to climb down a ladder and use a Bob-omb to break the Bob-omb Blocks next to the locked door, and then climb back up and wait for a Bob-omb to appear, and then quickly jump across some ropes to reach the Key. If the player moved fast enough, the Bob-omb will be below the player and they can drop onto it to ride it across the spikes and carry the Key to the locked door.
