The usual caveats apply -- this walkthrough represents a successful path
through the game, but probably not the most fun one. In fact, I've
included the solution an optional puzzle (the letter) because even
though it isn't necessary to completing the game, it's there to be seen,
after all. Also, there's plenty to do and examine, or at least that's
what I'm telling myself as I look at the several stretches of "z" that
seem to inhabit this walkthrough.

[... There's an element of randomness to this battle, so the number of
blasts it takes to defeat the creature may vary. The fog around the
creature's head dissipates after 5 turns, so refogging may be necessary.
