Adds some new mobs into the game that are biome specific. Some provide useful loot, some are… mysterious.

Type of Mobs

Wanderers (10 different variants, including a wandering merchant.)
Trojan (A large cow, perhaps more then it seems…)
Mummy (Desert husks but stronger, afflicts nearby players with slowness. Might have good loot.)
Cactus (Be careful when mining cactus.)
Basalt Delta Blazes (Blazes now spawn in the basalt delta as well!)
Piglin Giants (Large hulking brutes, they pack a mean punch.)
Hellfires (Large blazes that fire normal fireballs. Youch!)
Ghostly Phantom (???. Appears in warped forests.)
Ender Beast (A large ender beast that periodically spawns in the end.)
Ender Soul (An accumulation of ender dragon souls flying together. Shoots dragon heads.)
??? (???. Related to Ghostly Phantoms.)
