I sculpted a turtle that looked like the following picture out of RK covered in fondant. It's a little on the heavy side. It's approximately the size of the top layer. My cake's inspiration looks like the image at the very bottom.

The design difference is that the first layer is going to be an blue airbrushed covered fondant layer. The second layer will have the waves as shown. Now I want it to look like the turtle is floating on top of the waves without it crushing them. How would you achieve that?

The turtle will need to be on a board with dowels under it. I'd probably cover the whole board for the turtle with blue fondant, cut the dowels taller than the tier they're sitting in, and then wrap some of the waves around the dowels. If you're transporting it assembled, you'd probably have to put the turtle on when the cake reached its destination.

What if I made another fondant cake just underneath dowries into that? Would that work?
