In Caustic Caverns, around the Guardian Ruins near the end of the map, there are 'dirt blocks' (from Minecraft) around a cavern to the right and under the minecart used for ' Minecart Mischief.' After performing melee attacks on the blocks, one will encounter several creepers and a badass creeper, which are also from Minecraft.

One of the rifle challenges is called 'This is My Rifle,' which is part of a familiar line from the movie. There are multiple references to the movie Full Metal Jacket spread around the game.

If you turn right from there, you should see some stone and coal. Attack it a few times and you should be able to push through, provided it is 2 blocks high. Jump over it and land on some earth, then proceed right from there to find dirt that looks like something you might find in Minecraft. You should spot a stone shaped like a cube. In the Minecart Madness side quest, turn right from where you find the mine cart. Play until you reach the Caustic Caverns area.
