They want to reenact the town musicians of Bremen, and so Frieda Fuchs stands at the bottom, the crab is on top of Frieda, the crane is on top of the crab, the opossum is on top of the crane, and the opossum carries her babies on her back.

担 = 扌 + 旦 : Don Quixote had a terrible night and needs one coffee more this morning. Carrying a toy claw over his shoulder, he carries two really large mugs at each end of the claw through anthill's bathroom, using the claw as a shoulder pole.
