Comment It's a surprise cake.

Yellow Bee Cake Company ...

Thanks all! <3
WhiteCrafty, the couple loved diving. I think it was their passion together. The initial consultation was just for a white cake with some gems and purple ribbon, but when I went to meet them they told me about their love of diving, so we came up with the idea of having the diving scene hidden away at the back, so that it could be revealed and they would shock the family.
