Block 2

Block 2 (aka "See 33 Block") was previously the ID used for dirt blocks until the inventory was created, modifying the IDs of Dirt and Grassy Dirt, which have become 33 and 1.0625 respectively. It appears to be a black block with the note 'SEE BLOCK 33,' which is the ID of dirt. Blocks 1 and 2 are not seen ingame, but are required for the game to function.
