Acid Rain

Acid Rain is a disaster in the game.

Symptoms
In the "Acid Rain" disaster, once you get to the island storm clouds will cover the sky. When the acid rain hits, the walls will turn bricks, exposed to the sky green, white or grey.

What to do
After the popup message confirms it is acid rain then you will have to find shelter in structures like houses or buildings (have roofs, if destroyed find different shelter). If there are no structures, hide under trees as they have many levels. Green drops will rain from the sky, resembling acid which will kill you in a few seconds.
