Well the Australia thing was supposed to be at DAK. ; Either that or the finally-going-to-happen Beastlie Kingdom that they said would be part of the Kingdom...(and still lives on on benches and as a part of a stone dragon on the river).
Personally, I always thought a Russia pavilion would be cool - everyone knows the spiral church designs and Red Square...and Vodka and caviar tastings, borscht soup & potatoes would be easy to serve!
