Danger Valley Ducks

7777 is the only number. No more, no less. Stake Ducks, trade Ducks, hold Ducks, quack with Ducks, be a Duck. Are Ducks dangerous? No one knows. Are the Ducks real? For quack sake yes! You're a Duck. I'm a Duck. We are all Ducks. But besides us, there are some who don't understand what a quack is. Do you know what "quack" means? Only Ducks know.
