Poke Isles Cobblemon Sizes expands Cobblemon’s size system by giving wild and bred Pokémon distinct, persistent size variants.

Each Pokémon can be assigned one of six size tiers:

Teacup
Extra Small
Small
Normal
Large
Extra Large

A Pokémon’s assigned size is stored permanently, ensuring it retains the same scale after being caught, recalled, sent out, traded, evolved, stored, or transferred between compatible systems.

Teacup Pokémon

Teacup Pokémon are the rarest size variant and receive a special ability: they can ride on their owner’s shoulder.

The mod includes fallback shoulder rendering for Pokémon that do not normally have a dedicated shoulder pose, allowing a much wider range of Teacup species to accompany their trainer.

Only Pokémon assigned the Teacup size tier receive this expanded shoulder-mounting functionality.

Size Marks

Non-standard size variants receive a matching Cobblemon mark:

Teacup Size Mark
Extra Small Size Mark
Small Size Mark
Large Size Mark
Extra Large Size Mark

These marks provide visible recognition of a Pokémon’s size and can grant titles such as:

“the Teacup”
“the Extra Small”
“the Large”
“the Extra Large”
Normal-sized Pokémon do not receive a size mark.

Wild Pokémon

Wild Pokémon are automatically assigned a size when they spawn.

The default distribution makes Normal Pokémon the most common, while extreme sizes and Teacup Pokémon are considerably rarer. Every tier’s chance and scale range can be adjusted through the configuration file.

Breeding and Size Inheritance

Size variants can be inherited through breeding.

If one parent has a non-standard size, the offspring inherits that size tier
If both parents share the same non-standard size, the offspring inherits that tier
If the parents have different non-standard sizes, the offspring randomly inherits one of them
If neither parent has a non-standard size, the offspring receives a newly rolled size

The selected size can also be displayed in the lore of supported breeding eggs and baskets.

Configuration

The mod automatically creates:

config/pokeisles-pokemon-sizes.json

Server owners can configure:

Whether the size system is enabled
Whether breeding inheritance is enabled
Whether eggs without parent data receive random sizes
Whether size marks are enabled
The chance of each size tier
The minimum and maximum scale of each tier
Height-based scaling for Teacup Pokémon
