>>8893174its called usually something like mochi plush. I have a molang with it. (anorher simplistic design i feel works) It seems to be becoming more common in toys but i dont know if theres another brand who do it exclusively.
anyway what i feel about squishmallows is that they are just cute pillows, and i wouldnt mind getting a couple of the large ones for that purpose. but they do lack the little spark that makes my other plush so loveable.
