Pooplant

From 2speccers2tools wiki

The poralp tree, despite only just having become multicellular, has already found its way onto land. unfortunately, it lacks any proper cell wall, so it's basically just a floppy land seaweed. In order to keep itself from completely drying out it has developed an outer layer of cells containing keratin, functioning as a thin and especially poopy cuticle. The pooplant has also gained true roots in order to pathetically leech nutrients from the soil.
