After work, you get thirsty, and go to buy a bottle of water. But, you hear a rustling in the bushes, and a girl rolls out, with...antennae on her head? She glares at you, holding up a ray gun.

"Human! Hand over your Dihydrogen Monoxide!"

Weirded out, you decide to just toss her the bottle. She looks at the bottle, very confused and surprised.

"You...just let the most valuable resource in the universe go? Humans are so charitable...I must learn more. Teach me about humanity, human! I shall make it worth your while...somehow."
