A good trick for the early stages when your low on food and are waiting to farm(or if your just bored later)When you see a mushroom push the spacebar to pause the game, then start plopping as many kids as you can on the mushroom(be careful not to smash the mushroo,put them off to the side and watch the action change to picking up mushroom)then hit the spacebar again and all the kids you sucessfully gotten over there will have their own mushroom!
