活不下去

活 = 氵 + 舌 : Helga Horse joined the traditional water bottle challenge and empties a bottle of water over herself in the observatory's kitchen. To raise the difficulty level, she only uses her tongue to hold the bottle.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

下 = 一 + 卜 : Mnemonic symbol: from the up/down logic, and a little bit the shape of the character, a ladder.

Xi Shi (xi) is on a retreat in the ashram. Using a voodoo staff (卜), she divined that next (下) week she'll have to play the flute (一) sixteen hours per day. Because she hates playing the flute, she climbs over the ashram's bathroom (a4) wall using a ladder (下) to escape.

去 = 厶 + 土 : Mnemonic symbol: The "nose" part (厶) can be seen as an arm, which goes through "earth" (土), and this reminds me of some protesters who lock themselves (or their arms, to be specific) to concrete barrels. Cupids dirt capsule could also be a concrete barrel. So in other characters, I'm going to represent 去 by a concrete barrel.

Cupid (qu) is trying to send himself to earth. In the bathroom of the space station (Ø4), he has prepared a capsule made of dirt (土). He's wearing his lucky fake nose (厶) when entering the capsule.
