Well, I finally made the cake. It was quite a challenge!. I think the eyes should have been closer together, but it was too late to move them when I noticed it. I used three 7" layers and the half ball pan. Decorated with buttercream and made fondant body parts. I put toothpicks in all the body parts just to be sure they stuck!
They were really pleased with it. I don't think I would want to attempt it again though!
I just posted the pictures.
