Harvest Festival seeds are items won on Treasure Hunter during the Harvest Festival promotion. They can be planted in sets of 5, 10, 25, and X, anywhere where logs can be lit, to grow a Harvest Festival plant. Each seed used makes the plant last for an additional 12 seconds, and a maximum of 25 can be planted at once to grow a plant lasting a total of 5 minutes. If the option to plant X is selected and 0 is entered, players get the message "You attempt to plant 0 seeds but to your surprise nothing happens."
