Obtaining the first Big Mushroom is a random event that can only happen in the Fall. On each day of Fall there is a 5% chance of a spawning event being triggered. When triggered, the game engine will choose 10 farm tiles at random. If any of those ten tiles have a fully grown, untapped forest tree, then that tree will transform into a big mushroom. | Obtaining the first Big Mushroom is a random event that can only happen in the Fall.
