The three-kernel detriti replaces all cilia detriti except for those with a mutualistic relationship with Vinagob. It has developed a third nucleus, causing it to have a distinctive 3-pointed star shape. The duplication causes it to have an overall flatter shape and twice as many cilia, which simultaneously makes it easier for ocean currents to pick it up and carry it to new food sources and allows it to swim a little against the current when food is located. The additional nucleus also means it has a much larger genome, though it does not yet do anything with this. It is otherwise identical to its ancestor; it is a unicellular scavenger which converts sugars and oxygen into carbon dioxide.
