A Latter-Day Litter Letter
You tromp along the coastline for a while, looking for the alchemist's washed-up gunpowder shipment, but not finding anything of value. Suddenly, you catch a glint of sunlight on something shiny. Brushing away the sand, you find an old Cloaca-Cola bottle, with a piece of paper inside.
You fish out the paper and unroll it. It reads, "Help me, I'm trapped inside a Cloaca-Cola bottling plant!"
Huh. Well, at least you can get the deposit on the bottle.
You acquire an item: empty Cloaca-Cola bottle
You fish out the paper and unroll it. That's odd -- it's blank. Why would anyone send a blank message in a bottle? I mean, even if they couldn't think of anything else, they could've written "The weather is nice, wish you were here."
