My DS has asked for a digger cake for his birthday - Holy Cow!!! I'm fairly sure I have it planned in my head but I am struggling with what to do for the arm & bucket. My plan is to make it out of icing but I don't know what the icing is called or where I get it from - off to a good start, LOL!!
So what is the icing that you can make figurines out of? And where can I get it?

Thanks.
