LotsOMobs adds more than 25 new mobs to Minecraft including birds, fish, lions, mammoths, snakes and even dinosaurs. As well as making the Minecraft world much more interesting to explore, many of the mobs have unique drops, for example deer fur can be used to create armour. Camels, mammoths and pterosauruses can all be ridden in the same way as horses in vanilla Minecraft.

The mod adds several new biomes to Minecraft where you can find many of the new mobs. Penguins and polar bears spawn in the Antarctic biome, all species of dinosaur spawn in the dino biome and giraffes, elephants, lions and vultures spawn in the savanna.

LotsOMobs also includes two human NPCs; cavemen who appear in the dino biome and eskimos in the Antarctic biome.
