Based on Duke Caboom from Toy Story 4, the figure on top of my Isaac Caboom cake was supposed to do a daredevil jump off the end of the cake. Like many of my cake mechanisms, it sort of worked eventually, but not as well as I had hoped. Which is pretty on brand, both for me and for Duke Caboom.
The cake is lemon cake with raspberry mint white chocolate ganache. The red, yellow, and orange piece on top is isomalt. The guy is made out of gum paste with royal icing detail piped on top.
