This level will pit you into a rematch with Hisstocrat, which is a fight that’s mostly the same as the previous one you had. Hisstocrat is a serpent and will appear out of the ground. In order to deal damage to him, you need to jump on top of his head. The problem arises that the boss is too tall, so you need to find a way to reach the top of his head. That comes in the form of smaller snakes coming out of the ground, with plates on their head.
You can stand on these, although sometimes the snakes will not have plates on their head. Normally, you’d either use the snakes as stairs to reach high enough, or use a Cat Suit to climb the taller ones. After damaging Hisstocrat, he will dive underground, pop out and rain down fireballs, leaving small puddles of lava on the ground. That is the only difference between the two battles, as they were boulders in the first one. You might find a Super Bell on one of the smaller snakes sometimes, which helps a lot. After three hits on Hisstocrat, you will finish him off, so grab the Green Star, then finish the level.
