The paca has two or three textures on their body. Each texture needs to be present over a large enough area on the paca's body. Textures can only be within the rarity of a paca (eg; a rare paca cannot have mist and crystals, but they can have transparent and mist).
The pacapillar has four or more textures. The pacapillar can have any number of textures above four, but they must all fall within the rarity of the paca, and must each cover a significant area on the pacapillar.
