I'm hoping to make a cake a bit like this one for dd's penguin-themed party.
I've made fondant penguins before so I'm reasonably confident about those, but I'm not sure what sort of icing they are using for the 'body' of the cake (ie the main white round cake). Would royal icing with added glycerine work to get that snowy look without being too hard?
Also, what do you think they used for the entrance tunnel to the igloo? Do you think it is just a non-edible tunnel covered in fondant, or would there be any way to make a hollow tunnel like that out of something edible?
