* Castform is the lightest Pokémon.
* In Mystery Dungeon: Explorers of Time, Darkness, and Sky, Castform has a body size of 4, despite it being a body size 1 in and having the same in-game sprite in Explorers of Time and Explorers of Darkness.

===Origin===
Castform resembles a living and acts like weather in general, but it may also be based on a . It is similar in both concept and design to a , a Japanese charm doll used to wish for good weather. Its forms and their types may have originated from the English saying "rain, hail, or shine". Its shape of a large sphere with two smaller orbs resembles an H2O molecule, matching how it is said to be composed of molecules similar to water.
Conceptually, Castform may also draw inspiration from or be intended to contrast with the concept. These are stones jokingly hung up as a low tech way to tell the weather. They are intended to parody the poor forecasting of more complicated modern instruments. Given Castform's artificial origins and design to predict weather, but failure to transform until after the weather is already present, it may be comparable to the opposite extreme of a weather rock.
The Sunny Form looks like the on a cloud, the Rainy Form resembles a droplet of rain on a dark cloud, and the Snowy Form looks like a gust of wind or an ice cream cone.
====Name origin====
Castform may be a combination of forecast (the prediction of weather) and transform or form (referring to its ability to change form depending on the weather).
Powalen may be a combination of ポワン powan (onomatopoeia of a sudden transformation, similar to "poof" in English) and 変わる kawaru (to change or transform).
