Simisage is a simian Pokémon that is primarily green. It has a pointed, bush-like crest on its head similar to a pompadour. The leaves that grow on this crest are bitter. Its ears are broad with light green insides, and it has oval eyes and a black nose. Simisage has furry, white eyebrows and shoulder tufts; and a cream-colored face, chest, hands and feet. Its hands have five fingers, and its feet have three toes. Its thorny tail is long and tipped with leaves.
Simisage is based on a monkey and a tree; the fact that it is based on both may mean it might be based on the legends of monkey trees or possibly a visual pun on leaf monkeys. Its hairstyle may have been inspired by the bōsōzoku or yankee subculture.
Simisage is a combination of simian and sage. Sage may either mean a type of plant or a wise person, the latter possibly relating to the "three wise monkeys" motif of the elemental monkeys. It may also come from the German word sagen, meaning to say.
Yanakkie may be a combination of 柳 yanagi (willow) or 野菜 yasai (vegetable; an alternate reading of 菜 is na) and monkey. It may also involve ヤンキー yankee (delinquent youth) and けっき kekki (vigor).
