足 = 龰 + 口 : Mnemonic symbol: a football. Zapatista Zebra (zu) wants to pimp his football (足) in the space station's kitchen (Ø2). He thinks that a few more vitamins wouldn't hurt, so he extracts the vitamins from a mandarin (口) with a syringe (龰) to inject them into his football.

啇 = 立 + 冂 + 古 : Dorothy Gale (di) bought a cloister (古) and wants to set it up in the space station's bathroom (Ø4). The package contained a vase (立), a stem (啇) and a manual showing how to combine the two items to get the cloister (a map 冂 in a metaphorical sense), but Dorothy has no idea how to set up her cloister.
