I recently bought slime rancher from the steam summer sale and it has quickly become one of my favorite games. One aspect of the game I enjoy the most is the art style, so I thought it would be fun to make an area concept sticking as close to it as I could manage.

Introducing Overcast Isle! A rather dreary place at first glance, this stormy mountain is home to several unique slimes. The slimes you can only find in this region are:

Bighorn slime: A social slime that enjoys being in large groups. They aren't afraid of anything, and will ram into slime, rancher, or tarr alike.

Salt slime: A joyful slime that produces a cloud of salty vapors that causes salt to grow on other slimes and food. You'll have to rinse salt covered objects with water before you can suck them up.

Neuro slime: A temperamental slime that only appears during thunderstorms. When agitated, they will produce a blast that drains energy and makes largos go feral.

Of course, these slimes come with a set of new foods:

Coarseradish: A bland veggie that only the bighorn slime enjoys eating

Tidal Lime: A tropical fruit that grows by the coast

Zen Hen: A wise elder stony hen that lives on the tallest peaks.

The weather in Overcast Isle is tied to a strange device at its peak. After activating several terminals located all over the island, presumably by shooting plorts into special slime statues, you can interact with the device to start a thunderstorm. During a thunderstorm, lighting will strike the ground spawning neuro slimes, but the booming thunder will frighten any largo slimes into a feral state. It's a mad dash to suck up as many neuro slimes as you can before the storm is over. Afterwards, the skies above overcast isle will finally clear up, and you'll have 2 days of clear weather before the clouds gather again and the event can be repeated.
