Layout
Mario starts at the bottom of the stage with two ladders he can climb and a sleeping Sairesu which will wake up and charge at him if it hears him land so it's best not to jump and just climb up the ladder on the right. Then Mario can jump up and take the Hammer to defeat the next Sairesu. Mario must then climb up the next ladder where if he jumps over to the platform on the left he can get a 1 UP Heart but he must be fast and go back to platform he came from as there is another Sairesu which will quickly charge at him. Then he must climb up another ladder and he can either jump to the platform next to it or climb up the next ladder that goes to the platform with the Door no matter which way he goes there is a Sairesu. Mario can make it easier by going to the platform from the right to wake up the Sairesu so it charges to the right then he can go back around then grab the Key then quickly throw it up the platform with the door then quickly climb the ladder before the Sairesu gets to him. Then all he has to do is grab the key and take it to the door to end the level.
