Moving cake

The firm where my mother works moved to a new location last week and wanted to celebreate with cake. I searched high and low for ideas, but didn't just want to make a moving box, so came up with this overturned version. The red book says 'register' (same spelling in Danish and English), the green says 'expences' (crossed out) and below 'profits' and the yellow says 'customers'. The small white foam things (I don't know the right term) are mini marshmallows, everythings else is made with fondant. The cake is 6x8 inch chocolate mudcake with vanilla buttercream and raspberry jam.
