The ancient Numenorean sorcerers tinkered with life forms on occasion leaving as their only record ancient scrolls. The kelpkraken consisted of a good dozen sea weed tentacles, each about 20' long, surrounding a core of stinking, compressed plant fiber that passed for a mouth and gullet. It tended to collect objects that could serve as a form of makeshift camouflage, and half its tentacles would, at any time, be decorated with old helms, human skulls, and various pots and other containers it had picked up off the bottom of the sea.
