啬 = 土 + 丷 + 回 : Mnemonic symbol: stingray.

The stingy stingray (啬) and the mean crocodile (丷) want to return (回) to the river using the elevator's toilet (e4), but lots of dirt (土) is blocking their way. They ask the elevator's boss Socrates (s) for help, but he doesn't make his hands dirty so he starts a boring monologue about living as an expat. As the stingray and the crocodile realize he won't help them they start crying out loudly.

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).
