Oh my goodness, it's so cute! I wish I could help with pricing.. but I don't really know much about it. But you should definitely be getting a bunch of money for that cake! It's just adorable!!
Anmy way you look at it, that's a double topper. The figure is one topper and the game controller thingie is a second topper. That's a minimum of $80, PLUS the cake.
Thanks so much that really helps!
