For DD we made a 1 with hot pink icing and covered in Smarties.
For DS I made a Mickey Mouse...TBH wish I'd gone with my first instinct and made the electric blue 1 with smarties.

1 is really easy - it's only 2 bar tins cut to make a 1.
I have also made/had Noah's ark, a 3D dragon, a star, a moon, a toadstool, whale, cup cakes decorated (there are some awesome designs for those), a monster, a car...ummm love the WW cake books but there are heaps of others too.
