Cobblemon Spawns: Ultimate Location & Rate Tracker

How Cobblemon Spawning Works

Cobblemon spawning is the system that determines which Pokémon appear naturally in your Minecraft world. Each Pokémon has one or more spawn entries that define exactly when and where it can appear, based on a combination of biome, time of day, weather, light level, and world structure.

Biomes and Spawn Conditions

Every Pokémon spawn entry is tied to one or more biome tags — categories like is_jungle, is_ocean, is_mountain, or is_nether. These are not always the same as Minecraft's named biomes; they are broader tag groups. A Pokémon that requires is_freshwater, for example, can appear in rivers, lakes, and other water biomes that carry that tag, not just a biome named "river."

Beyond biomes, spawn entries can require specific conditions such as time of day (day, night, or a specific in-game hour range), weather (clear, raining, thundering), light level, Y-axis range, whether the sky is visible overhead, and nearby blocks or structures like strongholds, ancient cities, or woodland mansions.

Rarity Tiers

Each Pokémon spawn entry belongs to one of four rarity buckets: Common, Uncommon, Rare, or Ultra Rare. Within each bucket, a weight value (typically 0.1 to 10) determines how often that Pokémon appears compared to others in the same bucket. A higher weight means more frequent spawns within that rarity tier. Ultra Rare Pokémon — including most starters and pseudo-legendaries — have low weights even within the Ultra Rare pool, making them genuinely difficult to find without knowing the right biome and conditions.

Spawn Context

Cobblemon uses three primary spawn contexts. Grounded spawns place Pokémon on solid land. Submerged spawns place Pokémon underwater or under lava. Surface spawns place Pokémon on top of a fluid like water or lava. Some Pokémon have multiple spawn entries covering different contexts — Squirtle, for example, can spawn both on the ground near water and fully submerged.

Using This Tool

The Pocketcraft Cobblemon spawn tool lets you search any of the 800+ Pokémon in the Cobblemon mod to instantly see its full spawn entry: which biomes it appears in, its rarity tier and weight, required conditions, level range, and spawn context. Use it to plan your hunts, locate rare Pokémon, and understand exactly what conditions you need to meet in-game.
