I've been thinking of putting a Cloaker in a campaign I am making and I want to use its trait False Appearance to hide. False Appearance is for the Cloaker is defined as:
While the Cloaker remains motionless without its underside exposed, it is indistinguishable from a dark leather cloak.
I'm thinking if a PC sees the Cloaker hiding, one may try to put it on; in which case I'm not sure how exactly to handle it. Would the PC get a perception check to realize it's actually a creature and if the PC fails, would the Cloaker remain hidden on the PC's back while the PC is moving?
