Yeah, it’s kinda nice to have a place like deserts to farm for gunpowder, but even Boomers are getting old (Sorry, no pun was intended). Here is a complete(ish) list of mobs that you can find in deserts:
Boomers
Rabbits
Crocs
Alligators
Sharks
Ocean Slimes
Lava Slimes
Dolphins
Tropical Fish
Salmon
Cod
Turtles
Sand Monsters
Sand Men
Humans
Human Traders (They are humans! They don’t trade in them!)
Zombies
Skeletons
and
Baby Spiders
So yeah lot’s of mobs but they are mostly all hostile or ocean/river creatures
Here is a list of mobs that would be nice to have in deserts:
Camels
Rattle Snakes
Lizards
Sand Spiders
Vultures
Evil Cacti?
