This, in case you're from the Moon, is Ms Pac-Man.
Built from corrugated cardboard, mount board, newspaper, glues of many kinds, paint, tapes of many kinds and some foam and felt for comfort. It was a prize winning costume, due to, as usual, me not realising the scale of effort I'd gone to, compared to everyone else. Despite it being the scourge of my life (certainly the scourge of my living room) for a few weeks, I became quite attached to it. She was a party hit, and I was implored to not throw her away, so she now greets me with her toothless grin at the top of my stairs of the way to bed each night.
