Underwater travel.
You find yourself underwater, far away in some open sea (How? Make it up yourself.) and realize that you can breathe (How? Make it up yourself.)! What will you do? Explore, admire, get to know, help, find your way back?
You can be a pirate who ate something and then drunkenly fell overboard, or an ordinary person who had a sunstroke and fell into the sea and he was carried away...
The bot is rather aimed at people with a visual imagination who want an immersive experience ig.
