吉普

吉 = 口 + 士 : Mnemonic symbol: "Giga" stems from a Greek word for "giant", so I'll represent 吉 by a giant.

吉 = 口 + 士 : The giant just arrived at the space station and is very hungry. In each hand he holds Joan of Arc and the bachelor captive and robs them for their mandarins which he longs for.

普 = 並 + 日 : Mnemonic symbol: 斯普特尼克, Sputnik the satellite.

Petra Penguin is really angry at the sun for heating up earth's poles. In the space station she tries to kill the sun with a combine harvester, but the sun defends itself by flinging Sputnik replicas at Petra.
