The pacapillar's limbs are replaced by small fins. These will not turn a standard paca into a gilled paca, and cannot be long enough to resemble those of a gilled (ie; not large enough for a paca to use them to swim with). They can be any style, but must fit the rarity of the paca (if a paca cannot have holes in their feelers, then they cannot have holes in their fins). The fins must also be the same texture as the pacapillar.
