Sentient Seaweed

Every so often, stray elemental energy possesses not only Isopups and other biological entities, but plants and other species of flower as well. One of the affected is famously labeled sentient seaweed- despite the name, it cannot talk or form coherent thought. It, however can see and eat physically, despite it being photosynthetic. Usually, sentient seaweed are more-so tricksters, once something entangled in its vines it will drag it down to the depths, making sure what it is. If the object it has gotten is smaller than a coconut, it attempts to eat it. If not, it usually lets the creature go and hides.
