Seedrian

Seedrians is a name used for a species of plant-like aliens who have evolved to assume sapience and a humanoid form.

Biology
Male Seedrians; referred to by some as Thorndrigans; are slightly larger than most of the inhabitants of Sonic's world, and are usually rather round, with short tails, small antler-like growths on their heads, and a colored ridge on the top of their heads; they are largely similar to trees in their make-up. Female Seedrians, or Petali, more closely resemble their plant ancestors, being mostly slender and having an arrangement of petals sprouting from their waists and buds — or bloomed flowers — atop their heads.
