鞭闢入裡

鞭 = 便 + 革 : Brunhilde (bi) is working on her skill with the whip (鞭) in front of the anthill (an1). She spans a cow's hide (革) like a trampoline and throws her mobile phone (便) on it. She then starts to whip (鞭) the mobile phone up and has it jump on the cow's hide just for fun.

辟 = 尸 + 口 + 辛 : Mnemonic symbol from 辟邪, to ward of evil: a jade dragon, because this is what you get if you google image search 辟邪. Pocahontas (pi) stored some delicious kimchi (辛) in the space station's bathroom (Ø4), and a ghost (尸) is trying to eat it all in one gulp. Pocahontas is prepared though and uses a jade dragon (辟) to fend off (辟) the ghost. She does throw a mandarin (口) to the desperate ghost though.

入 = 丿 + ㇏ : Mnemonic symbol: an enter key like on a computer keyboard.

There is a special area in the space station's bathroom (Ø4) which is filled with bananas (丿), but you have to hit an enter key (入) to enter (入). Rachel Rhinoceros (ru) uses a finger (㇏) to press the button and get access to the bananas.

里 = 土 + 田 : Mnemonic symbol: a sunflower. The 田 part looks like the blossom and 土 looks like the stem and leaves. Li Qingzhao (li) wants to put up a field (田) inside (里) the space station's living room (Ø3). First she puts some earth (土) here and there, and then she plants lots of sunflowers (里).
