Feelers that are the height of the pacapillar including it's head but excluding it's feelers (or shorter). There are no limits on shape for tail feelers. The texture must be the same as the rest of the pacapillar unless a Multi-Texture mutation is applied. A Rare pacapillar can have 5-9, or zero tail feelers. The feelers can be arranged any way as long as they are within the tail area.
