Some more images of the Pakari misprint. In the third image it's the one on the left. I do think in this case it's a genuine misprint.
Mine came from a seller on bricklink so I couldn't tell you the source. Would you have any idea how rare these are as compared to the light blue version?
I recently came into possession of a normal dark blue Kaukau but it has bubble cheeks. I can't find anything about bubble cheeks Kaukaus in anything other than light blue. Does anyone have a mask like this, or at least any information about it?
