What role is this critter going to serve? I'd just use some other critter's stats and just pencil in Type: Humaniod (Human) or Monstrous Humanoid.
Neutral forest dwellers? Use the Ape stats with a slightly bumped INT.
Ally to PCs? Use bugbear stats
Beatstick to tear some HP off of the PCs? Use Brown Bear with a slightly bumped INT, describing the bite as a headbutt.
Multiattacking monster with cold aura? I'm guessing the yeti's stats from frostburn.
