I really truly enjoyed making this cake! It's 99% edible! WallE's head, neck, arms and wheels are all made of RKT covered in MMF. His body consists of 4 2 inch layes of marble cake with vanilla bean filling. I could have made him look more like a hunk of metal but it was for a little girl's birthday and I wanted him to look kind of whimsical. I love the expression of his eyes!
