@RecursiveNeuron Purely by eyeballing it I think it's "zebra" (lowest sum of the ASCII codes, and that's the shortest word), but I don't carry the ASCII code numbers in my head, caps are less than lower case and "z" is a relatively big number, so it might be one of the others.
@RecursiveNeuron Pikachu? Ordered by ASCII codes - so effectively alphabetical but caps precede small caps
