I made this for my son's 4th birthday. We put some animal candles on the top for him to blow out. I got ALL these great ideas from other users on CC. The back of the cake is a waterfall with candy rocks. It's butter cream and Toba's fondant (which I tried for the first time, instead of MMF). I also used scrumptious cake flavors that I found in the forum - banana with Nutella filling and chocolate with a chocolate chip cookie as filling. Cakecentral is the greatest! Thanks for all the wonderful ideas!
