Hei Hou (ヘイ・ホウ Hei hō?) is the sub-boss of Mushroom Hill Zone in Sonic & Knuckles, as well as its locked-on form, Sonic the Hedgehog 3 & Knuckles. It is fought at the end of the first act of the Zone.


Attack pattern

Hei Hou uses an axe to chop down trees, sending the resulting chunks of wood flying towards the player. If fighting him as Sonic and/or Tails, he gets his axe jammed in the bottom piece of the tree he was chopping and struggles to pull it free, only to go flying backwards once it comes loose. If Knuckles is the one battling him, he will use a slightly different attack pattern where the wood chunks will bounce, and his head will be used to attack, flying off to hit Knuckles before returning to Hei Hou's body so he can move on to the next tree.

Sonic Jam

In Sonic Jam for, this boss is featured as one of the bosses in the Sonic & Knuckles game. It is extremely easy now as there is only one tree (to the right), and the boss itself is very slow and chops at a rate of about one time every thirty seconds. In addition, the boss was placed lower so it could be visible on the screen, making it possible to simply jump at it.
