资

资 = 次 + 贝 : Zorro (z) has become a real capitalist (资). In front of the space station (Ø1) he locked a crab (贝) into a cube (次). Whenever he throws organic waste into the cube, the crab is so furious that it cuts the carbage to really small pieces and throws it out. Zorro then collects the cut garbage and sells it as organic fertilizer.

次 = 冫 + 欠 : Mnemonic symbol: the cube, as in words involving 三次 relate to "cubic equations" or "cube (third power)". The King of Chu (c) pulls a popsicle (冫) out of the cube (次) in the space station's bathroom (Ø4) and leaves an IOU note (欠) on the cube.

贝 = ⺆ + 人 : Mnemonic symbol: a crab. In the Eiffel Tower's bathroom (ei4), the Neanderthal man (人) and Beelzebub (b) are fighting a crab with staplers (⺆), but because the Neanderthal man (人) can't handle the stapler he accidentally staples himself in the forehead.
