Every day, Mama Duck paddles round the pond with her ducklings in a line. Every 30 minutes she finds a snack, and the duckling right behind her gets it. Then off it paddles to the back, so everyone gets a turn.

A duckling costs 0.0005 ETH and stays in line 3 days. A snack is 2% of the pot. Holders' ducklings get a double snack. Day 3 is picnic hour: a snack every 5 minutes. On day 7, every duckling still in line shares the rest. 80% of each duckling goes to the pot and 20% buys $PADDLE and burns it.
