Other than that, this generic soldier in Lord Vader's army was a combination of Rice Krispies treats (for the legs and base of the helmet) and yellow cake and vanilla Italian buttercream. The fondant took extra effort to apply, as the staff had to invent a "new technique of segmenting the cake and fondant to reduce weight and stress on the fondant." And, as the Stormtrooper was to be assembled on-site like a mannequin, the staff also created ways to make the cake completely modular.
The presentation of the cake was listed on the convention's schedule as "To Serve Man, er, Stormtrooper," though for true Twilight Zone effect, the Stormtrooper cake ideally would have inexplicably responded to questions like whether it was too short to be a Stormtrooper. In any case, when it finally was time, the cake was cut and pulled apart, one sliced block at a time like a giant Jenga puzzle. Then it was back to "Aliens in 20th Century Science Fiction Art," a Buffy the Vampire Slayer sing-along, and everything else in their journey through another dimension not only of sight and sound but of mind - and life-sized cakes.
