With the two ancestral cells in permanent symbiosis, the Poopyspite has entered the oceans and thrives as a result. The front half of the organism has developed cillia to manipulate detritus and small cells to be devoured. The long flagellum still helps it flee from predators and chase down prey. Additionally, it has developed the ability to feed on natural spite, much like the bruh cell except in small amounts. By incorporating the spite it consumes into its own tissues, it helps deter most predators such as goldy or el goblin. Since the Bruh Cell already feeds on spite, however, it is immune to this defense and as such is the main predator of this species.
