Players who like to collect rare species and forms in Pokémon may find a surprising one always out of their grasp: a particular form of Spinda is impossible to catch. Spinda is a plain Normal-type Pokémon that draws inspiration from a few different animals, including its rabbit-like ears and panda-like patterns. Its patterns give it a large-scale gimmick: each Spinda has an entirely unique set of spots on its head.
