Blue Roper

A monster possessing countless tentacles. Though recorded in the annals of time, it has yet to be determined even whether it is flora or fauna. The deepness of its color changes by its environment, which is thought to be in reaction to varying humidity levels. Not only is its body hard and resistant to physical attacks, it can also quickly regrow its tentacles after they've been chopped off, which leaves its red portion as its only real weak point.
