Mice Cake for Cayden

Li Ee wanted to have a cake with little mice for her precious darling - Cayden ., she didn't request for anything much - except a boy, mice and cheese bits.

Initally I wanted to do a normal 2 tier cake for her, but .. if I make the top tier to look like a cheese .. what should I put the 'cheese' on to ?

Then I remember I saw the milk carton cake before .. so I used 2 x 4" square cake pan which is equivalent to a 6" round cake to shape it like it, then bottom tier will shape like a cheese :

A ( 2 x 4 sq cake pans ) and a 9" Moist Chocolate Cake.
