OK, good.
Malleable Form (Ex): A busen can reshape its body into many shapes, although it always occupies the same volume and has an oily black skin. For example, it can grow large ears to give itself a bonus on Listen checks. A busen can use malleable form to grant itself a racial bonus on Balance, Climb, Escape Artist, Jump, Hide, Intimidate, Move Silently, Listen, Search, Spot, Swim, or Tumble checks. Malleable form can grant racial bonuses with a total bonus up to +12, but no more than a +8 bonus to any one skill.
A busen may also change the form of its natural attacks to take the form of any manufactured 1-handed melee weapon (heavy pick, shortspear, whip, etc.). The natural attack gains all traits of the weapon, such as damage type (bludgeoning, piercing, or slashing), critical threat range and multiplier, bonuses on disarm and trip checks, increased reach, and so forth. Regardless of the weapon emulated, the natural attack's damage is always the same (1d10 for a standard busen). Emulated weapons cannot be disarmed, sundered or thrown, since they are as much a part of the busen's body as any ordinary natural weapon. If a busen's natural attack takes the form of an exotic weapon, it sufferes a non-proficiency penalty unless it has the appropriate Exotic Weapon Proficiency feat.
A busen can change the weapon form of its natural weapons as a swift action (or a free action if it has the Quick Draw feat), but it requires a full-round action for a busen to change the racial bonuses of its malleable form.
