The One Who Punch U

The One Who Punch U spawns in caves and at night, and I accidentally made his spawn rate extremely high. He is hostile and opens doors when he feels like it. He also might break normal glass and glass panes because he doesn't like their color. The One Who Punch U doesn't drop anything, however he doesn't have a lot of health. Every time he takes a step, the cave ambience plays. His normal sounds are the bell sounds and if he gets hit, the sound that plays when you place an anvil plays. If you kill him, the sound that plays when you defeat the ender dragon plays as well.

The "Scaribiome" is a new biome that spawns wherever and somehow I messed up the code and "The One Who Punch U" doesn't spawn during daylight as planned. In this biome, the grass is red, the water is yellow, the fog is yellow, and the sky is black during daytime despite it looking yellow due to the fog. Dirt is also replaced with Netherite and there are a ton of gigantic spruce trees there. If you enter this biome for the first time; you get an advancement called "Ooo, very scary" and gain a lot of xp.

That's all the features of this mod I can remember off the top of my head.

UPDATE 1:

Revamped TOWPU and the Scaribiome among adding TOWPU's extended family members
