Zombie rage mode on horde night/horde night changes

[Adam the Waster]

When zombies spawn there would be a 30% chance that the zombie that spawns goes into rage mode, not just when they fall,

this would make horde nights harder cuz you got some crazy zombie just beating random blocks, on your base. or maybe it could be a random switch that just turns zombies into rage mode., 

new zombie spawns on horde night:

Mutated zombie (mid teir game stage) 

Crawler (every tier and always in rage mode) 

Zombie bear (late tier always spawns in rage mode)

Grace (VERY late tier, only one per night)

burning zombies: early

This is what I would like to encounter

Zombie Bear and Snow Bear - with white or light fur

Standard Wolves and Snow variation of Wolves - travel in packs rather than solo

A gang of feral burning zombies that move in Nightmare speed in the late game
