Whats a variant?
A variant is a differently-colored version of a species. For example, if you feed a turnip to a Whirlm, it changes color to a purple Whirlm. Each species has three color variants (one color variant for Pocket Paradise) which must be discovered through various means. Every time you discover a new variant, you are awarded more experience. Some main garden species also have arctic or desert versions that are differently-colored than their main-garden counterparts. These arctic or desert versions can also be varianted, giving some species a total of eight possible differently-colored versions. Snapshots comparing main garden and sub-garden variants can be found in the Variant Experiments thread.
