can i just use regular store bought in a box cake mix, or does the cake have to be denser??

Very pretty cake =)

That is made with fondant on the outside.. The cake itself is regular cake.

Here is a link that will explain how to buy and use fondant, as well as recipes for cakes like the one you linked =)

Edit: Yes you can use cake mix for it,just make sure the cake is cold before you start icing it.
