Cobblemon: Nests & Dens

Nests are scattered through the Minecraft world, and interacting with one gives the player a random Pokémon egg. Treats crafted in a Cooking Pot raise the chance of a given Pokémon type appearing in the egg. Eggs from nests and dens hatch after the player walks a set number of steps, and a Pokémon with Flame Body in the party shortens that count. When an egg hatches, the mod checks whether a matching type of Poké Ball is in the inventory, and one ball is used to catch the hatched Pokémon automatically. Hatched Pokémon appear at the player's feet.

Dens are a more advanced layer, inspired by Monster Hunter Stories. Medium nests give one egg and large nests give two, and dens come in four rarities, with higher rarities giving eggs with better IVs and EVs. Scents crafted and used in den cores raise the chance of opening a rarer den, and legendary dens carry a unique bonus. Fossil Nests can appear at any nest rarity and offer a chance at different fossil rarities. Dens are guarded by hostile Pokémon that cannot be caught, and after four to six searches the guardian awakens and attacks. Defeating it raises the rarity of the final egg.
