This was the graduation cake I made for my brother. The Nintendo characters are gumpaste. The piranha plant's pipes are RKT w/ fondant. WASC w/ buttercream and fondant accents. Top layer is Dark Choc. Fudge cake w/ choc. buttercream and fondant castle. Everything is edible. My sister helped make some turtles and leaves for the plants. I wanted to add more, but ran out of time (i.e. clouds, a Boo Ghost, etc...) Forgot to add white dots to mountains. My brother was afraid of the King Bob-omb when he was younger, it seemed fitting for his cake. Had fun doing this one!
