Pooplant
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.
