徙 = 彳 + 歨 : Marie Curie (xi) wants to change her residence (徙), but there is a barrier (歨, top) in the space station (Ø3) blocking her path. To get over the barrier she uses a syringe (歨, bottom) to pump up her black sneakers (彳) so she can just jump over the barrier and change her residence (徙) to the other side of the barrier.

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.
