The Sharkitten Den is a naturally occuring structure in Shipwrecked DLC, that spawns Sharkittens when open. It cannot be destroyed. It opens up during Monsoon Season, and appears as a large Sandy Pile any other time of the year. Periodically, a Sharkitten will spawn from these. If a Sharkitten is attacked while near one, it will retreat to the Den. Sharkittens also retreat to the Den at dusk. In addition, if the Tiger Shark is nearby, it will immediately appear to defend its kittens. The Tiger Shark will also outright attack the player within a certain distance of the Sharkitten Den.
