100% edible. All made from sugar and edible (except the fish bowl and smash plate cake). Green eggs and ham (baby's smash cake) and goldfish are on a rotating topper. Hat is four 4" layers stacked then 6", 9", 12". MMF. Baby also had Christening today so I put a small little cross in his hand. This cake took a LOT of time and it didn't help that I got sick early on in the week so ended up having to rush everything. I'm happy with how it turned out and they LOVED it!
