栗耳短脚鹎

栗 = 覀 + 木 : Li Qingzhao (li) is beating chestnuts (栗) off the Christmas tree (木) in the space station's bathroom (Ø4) using a knuckle duster (覀). She beats them so hard that the chestnuts open the very moment the knuckle duster hits them.

It ist what it looks like: an ear.

短 = 矢 + 豆 : Doggy Dog (du) is playing darts (矢) with some buddies inside of the anthill (an3). He ate a bunch of beans (豆) before, so every time he throws a dart (矢), he has to go to the bathroom for a short duration (短) to fart.

脚 = 却 + 月 : In the aorta Joan of Arc wanted to play a prank on the moon and kick him in the ass while he's inattentive for a second, but when she kicked him she just hurt her foot, and the moon didn't even notice. Silently, she retreats for now, limping on her hurt foot.
