古地磁

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.

地 = 也 + 土 : Dorothy Gale (di) operates the excavator (也) in the space station's bathroom (Ø4) to move a pile of dirt (土) out of the way.

磁 = 兹 + 石 : The King of Chu (c) broke open a mysterious, previously sealed rock (石) made of porcelain (磁) just inside the space station's entrance (Ø2). The rock contained a magnet (磁) which as soon as the King of Chu picked up was so powerful as to attract a Nimitz class aircraft carrier (兹), crashing the hull of the space station.
