Hi Arlette,
I think this is the diagram you're looking for:
Funny Bunny Ice Cream Cake. It's for an ice cream cake but I've made the same design using two round cake layers. Your request title is for a lamb cake so if you had something else in mind please feel free to post again.

Happy Baking!

Betsy

Many years ago I had directions for making a flat bunny cake, using square and possibly round pans, then cutting and decorating with frosting and coconut. I have lost the directions for putting this together. Any help on this?
