The levels starts off with Mario onto some blocks. Mario must grab the key, then land on the platform outside of water where he will drop it. He then must grab it again and take it into the water where he can use it to take out the two Gessori while avoiding the Bukubuku. Mario must then travel through the area the two Gessori were blocking, then jump out of the water and climb down the ladder. After jumping over a Purupuru, he then has to activate the road block and place it right underneath the door. After that, Mario must continue heading right; once at the end of the tunnel, he will find a ladder block which he must connect to an exit where a Gessori is. Mario must climb the ladder up to the top while the Gessori is not in his way, then swim up onto a lone big block on the right. He must jump to the next platform and activate the ladder block. Mario can place the ladder onto the right side of the lone big block which he can climb up to collect a 1 UP Heart. Mario must place the ladder onto the next platform after the one with the ladder block so it connects to the platform above it, then climb it back to where he started and quickly grab the key so he can carry it to the door to complete the level.
