Since everyone used to do that stupid Pie Vs cake thing. I think they should fit somehwere in the dark recesses of the code a hommoge to the planetside pastry wars....
With this I start you with my favorite: The intercontinental Balistic Pie cannon (my idea btw any use from actual pastry wars is purely coincidental. it's an idea I would love to see implemented in the real world I drool over the idea on a daily basis!
.. ). It cooks it cleans it fire 50 rounds a minute.
And secondly: The cake mobile. A giant armored vehicle with a clear open cockpit made of the strongest bulllet/laser/pie/pastry proof glass the world has ever known and always manned by the worlds finest in pastry chefs. Literally holding the Gods of the pastry world!
