骷

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.

骨 = 冎 + 月 : Gitta Giraffe (gu) is performing some dark rites in the space station (Ø3). She 3D printed a whole skeleton (骨) including skull (冎) and is trying to make it come alive under a full moon (月), citing from the Necronomicon.
