许

许 = 午 + 讠 : Xu Xian just loves having lunch in the space station. In fact he loves it so much that he calls mission control to get permission to praise it on an advertising column. After he got the permission, he smears his lunch all over the advertising column.

午 = 𠂉 + 十 : Willy Walrus (w) is having lunch (午) in the space station's living room (Ø3). He was hiding it in a secret location: With a key (𠂉), he can unlock a chamber hidden in the space station's cross (十).

Mnemonic symbol: this character looks like a big "i" (like in information), and I'll represent it by an advertising column. Maud Younger (y) gives a speech (讠) standing on top of an advertising column (讠) in the anthill's kitchen (an2).
