Coralshroom

This mushroom sprouts up wherever a coral dies, its spores are hydrophobic and latch onto dead corals to grow. Soft tissues of a mushroom will slowly grow outside of the coral branch and envelope it in mushroom fibre entirely. It develops spore sacks shaped like claws on the cap to deposit into the water flow when they are ready. The sacks will burst open when water has sogged it enough, and the spores will continue the cycle. Live corals can feed on floating membranes of this mushroom, making them perfectly symbiotic with the ocean. 

When fed to a Familiar, this item changes their form.
