古诺

古 = 十 + 口 : Mnemonic symbol: at least on German maps, this character actually resembles a cloister.

Oh no! Gitta Giraffe (gu) found that the golden cross (十) broke off of the cloister (古) in the space station's living room (Ø3)! She skewers a mandarin (口) on top of the cloister so that she can skewer the broken off cross back on to fix it.

诺 = 若 + 讠 : Nelson Newt (nu) sees an ad on an advertising column (讠) in the observatory's bathroom (o4) with a grilled chicken on it. He turns to his wooden chicken (若) and swears (诺) to protect it from anyone who wants to grill it.
