原 = 厂 + 自 + 小 : In the anthill's kitchen Yu the Great is modding a chocolate factory into a nuclear chocolate factory by powering it with an atomic bomb. Because it is hard to look inside the bomb through it's small opening, she uses a hand mirror to see inside and connect the wires. She also used a lot of daisies to decorate the bomb and underline her peaceful intentions.
