外宣

外 = 夕 + 卜 : There's a hole in the wall of the airplane's bathroom (ai4), and from outside (外), a bat (夕) wants to enter. Willy Walrus (w) is very afraid of bats, so he does his best to hinder the bat from entering with a voodoo staff (卜).

宣 = 亘 + 宀 : Mnemonic symbol: a big billboard.

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!!!"
