The turtle is a fruit cake with marzipan & icing, the front flippers and head are cake and marzipan, and the rear flippers marzipan only. The elephants are marzipan modelled on wire "skeletons" and the disc itself is marzipan and icing on a normal cake board.

My younger son did the base colouring of the turtle with food colours, and Jane finished it off with shimmer metallics. The disc landmass was done with food colours on icing, the mountains being marzipan. If you look carefully, there's even a Wyrmberg somewhere. Rimfall was achieved with liquid icing encouraged to dribble over the edge with a cocktail stick.

Once I get sorted out, I'll get some detail pix on Jane's website for anyone who's interested...
