These ducks spawn in small lakes or pond size bodies of water . I always find two or three in the lake that connects with the swamp on the southside of the map closest to the red avilus . Also beware of titanboa coming from hills and sarcos going into water . I suggest you take a bird and keep a close eye .
When you anger it. Don’t try to laugh because you will laugh. It looks even more pathetic than a dodo rushing at you and it deals LITERALLY 1 damage. Upgrading it to 200% means it only deals like 2. Don’t take it to fight.
