:
Mnemonic symbol: I think 曾 just looks like a firefly, with the head (with two feelers) at the top and the glowing body at the bottom.
The firefly is selling aloe vera out of a big wooden box in the kitchen of the Erechtheion. With a big microphone it is advertising the aloe. As it sees a mean crocodile and the King of Chu starting a big fight for the aloe, the firefly is very excited and states that it has never ever seen something like this before.
