A single pacapillar core turns into three pacapillars, all smaller than the default size of their subspecies (eg; a split paca is smaller than a standard paca, but a monster split, while smaller than a monster, will be bigger than a standard paca). Ultra Split pacapillars do not have to share a similar look, and can have more vague themes such as "love/the city" etc and look more different from each other.
