Stage 7-3

Stage 7-3 is the third level of the Iceberg in the Game Boy version of Donkey Kong. The level has an invisible door and introduces Purupuru and Penpens.

Layout
The level has Mario start on the ground to the left. Mario must climb up the ladder then go right, jumping across the blocks when the Purupuru are not in his way and making sure he's not on the blocks long as they can push him into the spikes, but he can stand on them and jump off of them to get up higher. Mario has to land on the platform with the ladder then climb it, on the above platform he must watch out for the Penpens as they can defeat him. Mario can use one of the Penpens to defeat the other by throwing it or he could use the key or he could avoid them, he must pull the lever to open the door (and activate the bridge) then he must grab the key then head out. Should he fail and the key goes back to its spawn point, he can use the block which is above the first platform or the spring block which is to the right of the first ladder on a slightly raised big block and place it near the platform the key is on to be able to get back up to the platform quicker. But with the key, Mario must once again jump across the blocks while watching out for the Purupru until he reaches the other side. Then Mario has a choice of either throwing the key onto the bridge then climbing up the ladder, flipping the switch to deactivate the bridge then quickly going down the ladder then going down to where the key went. Or he could keep the key and try to land on the block with the Purupuru and drop to the where the door is without falling onto the spikes. If he does either choice successfully he just needs to go over to the door with the key to complete the level.
