MOOMBA PARADE #2- CARNIVALE DOWNUNDER THE SEA- "BEHIND THE SEA"
The back of the costume had some kind of sea-god on it, possibly Neptune or somesuch. I can't recall exactly.
The 'fan' was a metallised cloth mesh held up by fibreglass rods concealed behind the 'seaweed' and fishes. The god was made from painted foam sheets, glitter and braid.
I never did 'get' the sea-god design. I think I would have done "Venus Rising From The Sea" if it had been me....
