Biology
Physiology
(From Bulbapedia) Sawsbuck is a brown and cream deer-like Pokémon with rhomboid ears and darker ear insides. Its eyes have light-orange markings that curve down to sides of its face. It has a dark-brown nose, and it sports cream fur on its chin and sides of its face. Light-orange stripes rim its underbelly, and its back is decorated with spots corresponding to the season: pink in spring, green in summer, orange in fall, and white in winter. Its limbs are slender and tipped with hooves. Unless it's summer, its brown tail points down. Sawsbuck lives in herds led by the Sawsbuck with the most splendid antlers. It can live almost anywhere as they adapt to the season, but prefer to live away from humans. It is herbivorous.
Its appearance changes depending on the season. During the spring, a tuft of cream fur appears on its chest, and its antlers are adorned with pink flowers. During the summer, its tail points up, it grows tufts of fur on the back of its head, and its antlers sport green leaves. During the fall, it sports a cream tuft of fur on its chest, and the leaves on its antlers are red and brown. During the winter, the cream fur turns white, tufts of white fur appear on its chest and lower limbs, and its antlers are coated in white.
(From Bulbapedia) Sawsbuck may be based on a Père David's deer, which is a species of deer that decorates its antlers with foliage during the breeding season. Its antlers may also be based on a deciduous tree. It may also be based on one of the stories of Baron Münchhausen, in which he tries to shoot a stag using cherry pits in his musket. The stag survives and escapes, and the next year he discovers a stag with a cherry tree growing out of its head.
Name origin
(From Bulbapedia) Sawsbuck is derived from sawbuck (a device for holding rough wood so that it may be sawn) and may be a combination of sawbuck and buck (male deer). Saws may also be an acronym for the names of the seasons (summer, autumn, winter, and spring).
