桔

桔 = 吉 + 木 : Zeus (ju) receives the giant (吉) as guest just inside the space station's entrance (Ø2). The giant says that she's hungry and Zeus offers her some tangerines (桔), but she already started eating the Christmas tree (木) she found in the corner.

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.

木 = 八 + 十 : Mnemonic symbol: a Christmas tree.

Malte Monkey (mu) is setting up a Christmas tree (木) in the bathroom of the space station (Ø4). He decorates the tree with eight-balls (八) and puts a holy cross (十) at the top of the tree.
