Anyone have an idea what the balls in the cake are made out of? Is it rolled fondant?

There are so many and such different sizes, I am guessing some of them are fondant or modeling chocolate, some maybe rice crispy treats covered in fondant and the largest ones appear to have a little nipple in the center, as though they are meringues.
It is an adorable cake. Actually, it has so many balls, I didn't even notice the small Teddies. Maybe a few less balls.
Some of them, the larger ones, may also be made from gelatin bubbles.
I don’t think any of these “bubbles”/“balls” are gelatine Sandra. If you enlarge the picture, and look closely, there all too big and firm to be gelatine. Gelatine balls are almost see through, and very fine in texture. I agree with kakeladi, either all fondant, or rct’s covered in fondant. A possibility of modelling chocolate, but most likely not. With this many bubbles/balls, modelling chocolate would get pricey.
