木 = 八 + 十 : Mnemonic symbol: a Christmas tree. Malte Monkey is putting up a Christmas tree (木) in the bathroom of the space station (Ø4). He's using a cross (十) as a base to put the tree on, and decorates the tree with eight-balls (八).

毳 = 毛 : Kitty Cat is looking at her fur using the mirror in the bathroom of the Eiffel Tower. She used lots and lots of additional hair for extensions, but it wasn't good for her fur at all: It's all crisp and brittle now because of the icy wind around the Eiffel Tower. Despaired, she eats lots and lots of crisps.
