A tentacled figure rose out of the fog, and hovered silently over the boat. It observed the entangled couple with the interest a child shows in a new game.
The girl opened her eyes mid-kiss, noticed the floating tentacles and leapt off the boy with a startled yelp. The boy looked around confused at the green mist that was now covering half their boat and tried to calm the girl, but his own rising panic was enough to send the girl into a crying fit of hysteria.
"YOU!" thundered the green tentacled figure and pointed at the girl. The girl stopped crying at once, her tears choked back by the fear of the unknown.
"It's bad manners," the floating form said, "to open your eyes when kissing."
Really bad manners.
