(Outdated description)
A part of the pacapillar is animated and can move on it's own. This includes aura, feelers, extrusions and prehensile feelers (feelers functioning as limbs). This does not apply to feelers moving to express emotion, but for parts that move independantly of the pacapillar. Feelers can change shape slightly; eg fire feelers can constantly move, flower feelers can bloom and wilt.
