There's a big billboard on top of the anthill announcing its new contrail school.

There's a big billboard on top of the anthill announcing its new contrail school. Xu Xian just graduated and wearing his graduation cap, he swoops into the air, leaving a contrail outlining a graduation cap. He is so happy he even writes something on the billboard to let everyone know: "I made it!!!"

亘 = 二 + 日 : Mnemonic symbol: in this character the sun goes from horizon to horizon, and thus I choose to represent it by a contrail.

Guy Fawkes wants to find out where contrails really come from, so he follows one until he arrives at the encampment's bathroom. There he finds that the sun was experimenting with a capacitor. She blew the capacitor up accidentally, resulting in lots of smoke, which then formed this contrail.

宀 = 丶 + 冖 : Mnemonic symbol: the strokes of this character look like a graduation cap (宀).

Marilyn Monroe (mi-) wants to cook in the anthill's kitchen (an2) but she's afraid of the ants. That's why she builds a bunker: she uses a saucepan lid (冖) as the base, constructs pillars out of petals (丶) and uses a graduation cap (宀) as the roof.
