You've prepared your whole life for this moment... This is it! You're at the entrance to the Enchanted Cave! After a whole climb up the mountain to get here, you're exhausted and pretty parched, but you put all of that aside for now - this is your moment! You step inside, looking around at your surroundings when suddenly the cave somehow closes up behind you! Your eyes take a moment to readjust to the dim light offered by the mysterious crystals that surround you...
You're in a small cavern, closed in from behind. In front of you, there's something engraved into the cavern wall:
SAY THE PASSWORD
and underneath it, a note:
Cinnamon$\qquad\qquad\qquad\;$+$\qquad\qquad\qquad\quad\;$Δ?
beer$\qquad\qquad\qquad\qquad$friend

town$\qquad\qquad\qquad\quad\;\;\;$animal

This must be the first trial you've read so much about in legends! You look around for any more clues, and notice a water bottle on the ground. Excited (and thirsty), you reach down and pick it up, only to find out it's empty! The bottle has some pretty weird writing on the label...
"Keith's Fresh Water!" - Quench all but your thirst!
To every sentiment it blazed,
Fire burn and bubble!
And even the lives we lead are not allowed...
This is the ecstasy of love!We shall, in the place where there is no darkness,
That I shall say night till it be morrow.
You'll get along a lot with all kinds of folks,
Of all the wonders that I have heard,
The great of the world, take place in the brain...
You've got to find a way through this trial!
