oh… well that kind of thing wouldnt bee in the faq sense on record we use other peoples headcannons so it wouldnt exactly bee ‘right’ of us to insert out feeling on the matter in that kind of place ya know.

but off record i personally think consistency a bulge would feel like pretty close to that of an octopus or the underside of a snail, but if you’ve ever seen one of those octopi that can shift how they look to be rough or smooth i think bulges work kinda like that. not saying they shift cause thats a lil much for me personally but different trolls can have different textures like having ridges an such.
