Trivia

 * Unlike in the Pokémon games of main series, Castform remains in the form it is captured as.
 * Castform spawns in wild in a form corresponding to the weather:
 * It spawns with Normal form when it's Partly-cloudy, Cloudy (overcast) or Windy.
 * It spawns with Sunny form when it's Sunny (clear weather).
 * It spawns with Rainy form when it's Rainy.
 * It spawns with Snowy form when it's Snowy or Foggy.
 * Castform in wild remains in the form corresponding to the weather at the time, that it has spawned, even if the weather changes, so it might occur that Castform's form doesn't correspond to current weather when player encounter it.
 * Coloring of Castform Candy was updated on August, 2018 to reflect more appropriate colors of Castform.
 * Candela's Sunny Castform can learn Hex and Energy Ball, which cannot be learned by Sunny Castform normally, and could be learned by Normal Castform.
 * Initially, Castform was the only Pokémon to have no shiny variants for its different forms other than Normal one. Sprite assets for shiny variants of Sunny, Rainy and Snowy forms were added to the game in September, 2020.
 * These shiny variants are also absent in the main core game series, until Pokémon HOME which was released back in February, 2020.
