Big Olaf cake for 1st birthday

Made this for a friend at my church who's little girl was turning 1. Its the 1st time I've ever incorporated foam into a cake. The cake is the bottom 2 tiers and that feeds 50 so needed something lighter for the head. I usually use rice krispy treats but I knew it would take a lot and be really heavy. I had to sculpt the head out of a round ball so this was a little hard since his head is oblong. I didn't quite get the top of his head right but I think it was enough to know who he was. All in all I learned a lot from the experience and I liked the results.
