Short feelers that are the length of the paca's head (or shorter!). For Snekkets, they must be no longer than their head.
These are simple shapes, including but not limited to; teardrops, cones, ovals. Not included; animal ears, wings, objects.
These do not have layers or holes. A common pacapillar can have 2-4 head feelers arranged in any way as long as they are around the head feeler area.
