大禹

大 = 一 + 人 : The big (大), huge (大) robot (mnemonic symbol for 大) is working out in the ashram's bathroom (a4). He's lifting a flute (一) to which Don Quixote (d) and Neanderthal man (人) are clinging.

禹 = 丿 + 虫 + 冂 : Yu the Great (禹) wants to impress Yu the Great (yu) in the space station's living room (Ø3) and studies a map (冂) of the world's rivers. After he decided where he want to build his dikes, he sends out an armada of mosquitoes (虫) carrying bananas (丿). The mosquitoes will drop the bananas at the determined positions and build dams with them so as to control the waters. Yu the Great is mildly impressed by these efforts.

禹 = 䖝 + 冂 : Yu the Great (禹) studies a map (冂) in the space station's living room (Ø3) to build his dams, but he's confused about all the new rivers which seem to have formed recently. In reality Yu the Great (yu) played a prank on him: she put a slug (䖝) on the map which just left trails of slime.
