I have made all the cakes bar 1 when my kids were young and they loved it.
1. Which one didn't you do- the duck? LOL
2. How did yours look? Chernobyled, like that guy's "duck", or good?
My mum used to make "Dolly Vardon" cakes every birthday. You make a cake in a pudding basin shape, you cut a hole, stick a barbie in the hole and then decorate the cake and the barbie like a fancy ballgown. Pretty easy to make, and we liked them.
