Kitchen failure AKA Lego brick or underside of a female pig?

Complete kitchen fail! I've been looking for geek food to serve at our party on Saturday. So far we have on the menu a Starship Meaterprise (which may turn out to be veggie), burnt Lemmings and some rice characters, as well as the obligatory Mr Potato Head.

But I saw this and wanted to make it:

How cool is that?

My practice effort... well, I decided to not go for dyed icing for the practice run which probably didn't help matters. The pink marshmallows I used weren't fully covered by the icing either. So when my eighter was complete it looked like it should have little baby pig cakes alongside it happily suckling from their mother's teats. 

I think I'm going to have to go with marzipan and ready to roll icing instead.
