Mnemonic
[c-] Casper is in the [4] bathroom of the [-e] electricity plant, where there is a huge sinkhole in the middle, full of electrically charged water 氵 spraying around. Casper gets a bunch of 刂 sabers and ties them together, and drops them into the hole, trying 测 to measure how deep the hole is so he can estimate how many 贝 shellfish he'll need to plug it and stop the dangerous electric 氵 spraying. He 测 measures it as being... very deep indeed. At least 100,000 贝 shellfish will be needed, for good 测 measure.
