Seedot is a small, brown Pokémon that resembles an acorn. A beige, mask-like pattern covers its large black eyes, and it has two beige feet. It has a gray "cap" with a short stem on top of its head. The stem is used to hang from tree branches in its forest home.
While hanging, this Pokémon absorbs moisture and nutrients from the tree until becomes too heavy and falls to the ground. The more it drinks, the glossier its body becomes. Additionally, Seedot polishes itself with leaves daily.
When released, Seedot will start walking right in the direction the Poké Ball was thrown. At certain intervals, it will perform Bullet Seed, firing seeds directly in front of it, similarly to a gatling gun, damaging any opponents in the bullets' way.
