A talented Pokemon fan imagined Eevee as a Rock-type monster, giving it an evolution of this type for the first time. The Pokemon franchise has introduced over a thousand of critters in its time, but Eevee remains much loved by fans. Introduced in Gen 1, this Normal-type is a fox-like Pokemon that became a hit thanks to its design, gaining so much popularity at the point of getting a holiday in Japan called Eevee Day.
