YDM's WeirdMobs

Thirty-one new mobs join the game, with fifty-six variations in total. Several of the creatures combine traits from familiar mobs: a Blaze Wolf ignites the enemies it targets and accepts blaze rods as a taming item, a Phantom Fox can be tamed with bones or cooked chicken, a Spider Llama fires poison spit, and a Wolfman spawns holding an iron sword that it passes on with a 20% chance. Ender Creepers run faster and charge before exploding, with a slightly weaker blast than regular Creepers. Blaze Creepers shoot instead of approaching and drop what Blaze Creepers would drop. Warden Dragons are smaller and weaker than the real Warden and spawn in swamps.

Spawning is controlled by a config file. Server owners can set which biomes each mob appears in, along with spawn rate, minimum and maximum group size and biome name. Changes apply only to newly generated chunks and worlds, not to terrain that already exists. The mod works with other biome-modifying mods through the same config. The mod is released under All rights reserved and is not open source. Files target Forge only, for 1.16.5 – 1.19.3, and the latest build is 3.0.2 for 1.19.3.
