The duck is a rare cosmetic item found during fishing. The item is very rare, having only a 1 in 250 chance of spawning. The duck is a reference to another game from the publisher, Axotl Games, called Scrap Mechanic. The design of the duck is reminiscent of the player character from the above mentioned game, particularly of the backpack. As of the latest game version, the item appears to have no practical purpose, but can be placed on board the raft as a decoration.
