㠯 = 尸 + 口 : Mnemonic symbol: 㠯 looks like a cool pair of safety goggles.

A ghost (尸) has been hiding from Maud Younger (Ø3) in a mandarin (口). Maud finds the mandarin in the space station's living room (Ø3) and squeezes the ghost out, and in order to (㠯) be protected from the mandarin juice flying all around in zero gravity she is wearing safety goggles (㠯).

以 = 人 + 厶 : So this is Neanderthal Man with a fake nose. He has bushy eyebrows, so my symbol for 以 is going to be one of these fake noses that come with additional glasses, eyebrows, and a moustache: Groucho glasses.

以 = 人 + 厶 : Maud Younger and Neanderthal Man prepared some costumes for Halloween in the space station. Neanderthal Man created a big fake nose, while Maud Younger made a pair of Groucho glasses.

此 = 匕 + 止 : These boots are made for walking! The King of Chu cannot get his boots off in the space station. First he tries with the help of a large ladle, then he switches to a big barrier, which finally works.
