The Mushroom is on the loose! One player, acting as the Mushroom, sneaks around the forest, hiding his movement from the other players in order to collect the crystals he needs to bring more fungi to life. The others play as the Seekers, a scout troop tasked with finding the stealthy Mushroom by using logic and deduction before he escapes with the precious, life-giving crystals. Are you tricky enough to outwit the Seekers as the Mushroom, or will you and your fellow Seekers deduce where the elusive Mushroom is hiding?
