昔 = 井 + 日 : Mnemonic symbol: From 奶昔, milkshake

In former times (昔), at the end of the day the sun (日) used to go down in a well (井) in front of the space station (Ø1). Xi Shi (xi) made the sun go out by pouring a milk shake (mnemonic symbol for 昔) over it.

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.
