First you need to unlock the empty street by probably talking to the old lady (at the main street if you go right) give her apple seeds and you will then unlock the empty street,by going left you see an old man,give him apple seeds too and you will unlock the dark street,there will be a beverage vending machine if you go right,which costs you 100 coins,so far the only drinks I know that work are Water,Milk,Apple,And Soda,they replenish a lot of your thrist, specially soda because it has a lot of varieties
