The fact that Scravsh have always had the ability to separate their body parts at will does not imply that they are always fully accustomed to being disarmed at inopportune moments or that the unconscious actions of their parts being separated or of the body itself being separated from the head causes them to stumble or have slight accidents XD

Such as the case of Wyven, who sought to relax on the coast of his village watching the sunset and the arrival of dusk to see the stars and try to mark them on a stellar plane with his telescope invented by him taking off his head and leaving it aside as he always does, however the passing at low altitude of a Cravay, a bird of prey native to his world caused his body to twist and with one swipe he accidentally threw his own head into the water.

Thanks to the fact that he always carried his fishing rod and there was no constant tide at that time, Wyven's body was able to pull his head out of the water without too much trouble, having fallen at an angle where he could still see himself from the shallow depth of the shore to be able to direct his body, being a somewhat painful moment for him but that did not prevent him from continuing with his goal of stargazing afterwards.
