The Swamp Rock is a cut-out stone rock found in the Swamp which has a pink stone hidden under it. Currently, not much is known about it except its history. Under the pink rock, there's a small tunnel leading straight into the ceiling of the River Tunnel.
It's located in front of a large 'peninsula' of rocks that jut out, making a bend in the creek. The initial rock is about three players high and five players long. This rock possesses every exterior property as the rest of the surrounding mountainside: Brown color with a Slate material.
Inside the Swamp Rock, upon using shift lock, the player can see a small, three-stud deep hole. Located inside the hole, a noticeably bright glowing pink block is found at the bottom, with the color being similar to Pink Vehicles. However, it does give off an awkwardly increased amount of steam than the rest of the Swamp. The Swamp Rock is likely a plug for the hole into the river tunnel, which may serve as a secondary way of accessing the tunnel if it is finished.
Prior to an update somewhere in November 2015, the player could have used Dynamite to blow up the Brown Rock off of the Pink block in order to access this. This was tested and proven to be fixed as of 1/2/2016.
However, during the time the player could access this block, it had some unique attributes. While the block is not affected by Dynamite directly, any loose item that came in contact with this block could not be interacted with anymore, no matter how many times dynamite is used.
