The Swamp Rock is a cut-out stone rock found in the Swamp which has a pink, glowing 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 is 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. The rock is brown, with a slate material, like any other rock on the Mountainside and Swamp.
It gives 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 January 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.
Interestingly, according to a leaked save of the game, the Swamp Rock is named as "BoulderRegen", and even has a script that regens the rock after a certain time it has been exploded. But as said above, this cannot be blown off anymore.
Even more, the pink block shown in the picture is called "NOTA_Boulder", which suggests that Defaultio wanted to add unique properties to this, but forgot about it afterwards.
