The townspeople are being scared awake by some mysterious moaning coming from the mountain. Bernard gets teased by his friends for being scared and takes up a dare to go up the mountain. Lolita and Diego go shopping and discover that a lot of fake money is being traded and causing conflict. After going up the mountain, Bernard and his friends find the fake coin operation (which is also the source of the "moaning"). The kids get caught, Zorro goes to rescue the kids, the kids destroy the operation, and the day is saved.
