贊嘆不已

赞 = 兟 + 贝 : The two FLOTUS (兟) visit Zorro (z) in the anthill's bathroom (an4) and as they see that he lost his rapier and has to fight with a crab (贝) as a weapon instead, they decide instantaneously to become his patrons (赞) and to pay him $1 for each defeated villain.

叹 = 又 + 口 : Tecumseh (t) is loosing a battle in the anthill's bathroom (an4). With each hit of his opponent's boxing glove (又) on his mouth (口) he gives a desperate sigh (叹).

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.

已 = ㇖ + 一 + 乚 : Kinda looks like a dredger. Maud Younger wants to dig a tunnel from the space station to earth, so she already used a dredger to dig up the walls just inside the space station. Unfortunately there are a lot of flutes built into the wall, and the dredger is of no use here, so she had to stop. Instead she then has to use a shovel and a sickle to scratch the flutes free and lever them out afterwards.
