Hisstocrat

Hisstocrat is a boss that appears in Super Mario 3D World as the boss of World 3-B. He is a large purple serpent wearing regal attire, such as a crown and cape. His name is a portmanteau of the words "hiss", a sound made by snakes, and "aristocrat", referring to his king outfit.

Hisstocrat serves as the second boss of World 3. Hisstocrat has only two attacks: one is to emerge from the ground to send boulders landing on the player. The second attack is to send out snakes with platforms for the players to jump on, which sometimes have Super Bells on them. When the platforms are cracked, the snake will bite and damage players if they stand on it for too long. Occasionally, Hisstocrat will send a snake without a platform to attack, which is telegraphed by the snake's eyes emerging from the ground first before coming up. His only weak point is the top of his head, where he has a large X-shaped bandage. The player must use the other snakes as platforms in order to reach this weak point, although it is possible for Luigi and Rosalina to jump on Hisstocrat's head directly without the need of platforms by careful use of the Spin Jump. Players can also throw their allies on top of the head. After three hits, Hisstocrat is defeated, and the Warp Pipe to the Goal Pole is revealed.

A female, fuchsia version of Hisstocrat named Queen Hisstocrat serves as the boss of World Bowser-B: Hisstocrat Returns. Unlike the king, she rains fireballs instead of boulders upon emerging from the ground, which leave temporary fiery puddles the player must avoid. She also spits fireballs as well.

In World Flower-12: Boss Blitz, both Hisstocrats are fought at the same time. In this battle, both will have fireballs raining down, and when one Hisstocrat is hit, the other will pause and cry, giving the player an opportunity to strike that one as well.
