Snoop, it must have got in during the production stage, there's no way thats just managed to work its way in there.
Not sure how to get it out, only thing I can think of is if there is any gap at all in the seams of the lights etc that you could maybe modify a hoover end like a henry to try and suck it out/through but apart from that I'm at a loss.
Pretty unfortunate and unlucky, it would annoy me if It was mine.
