I'm going to make a dinosaur or monsters inc cake

How would you do it?

For dinosaur I have these 2 ideas




How would you do the shape cake?the other is more straight forward

For monsters inc

I think I'd manage this sort ok



But he likes the turquoise and purple character more

So I thought this sort of thing but how the hell would I do sullivan??




Any other suggestions? I'm thinking dinosaur a bit easier but he likes monsters inc a bit more than dinosaurs although likes both!
