登場作品：
Don't Starve Togetherの大型アップデート、A New Reignで追加されたペットを作り出すための建造物です。Rock Denは小さな洞窟の奥から二つの目がこちらを覗いているような見た目で、Mosaicバイオームで見つけることができます。
使い方はAncient Pseudoscience Stationと似ていて、近づくことでCritters Tabが新規で追加されCritterと呼ばれるペットを作成することが可能になります。
作り出したペットはプレーヤーに追従しますが戦うことはありません。また、ペットはプレーヤー毎につき最大1体まで従わせることが可能です。別の新しいペットを従わせたい場合は先にRock Denの側で逃がすことが必要になります。
Rock Denは燃えたり破壊されることはありません。
