So, a while ago I sketched a picture of a mermaid that makes friends with a slime. The idea was that the mermaid can't leave the water, but she wants to see the world, so the slime offers themself as transportation! Now they're exploring the world together, seeing as many sights as they can manage!

Of course, sometimes they have run-ins with adventurers. Fortunately, they're more than capable of handling themselves.
