The Succulent Matress is a treasure in Pikmin 2. It is found in the third floor of the Submerged Castle. It was found near many electrical hazards, making your Bulbmin useful to retrieve it. The Succulent Mattress is actually a large marble cookie. It is so sweet to taste and touch, and if you sleep on it, you'll dream of a land of sweets.
