Block

The Legend of Zelda series
The block has appeared in nearly every Zelda game to date, each incarnation serving the same purpose- to be pushed or pulled. In the first Zelda game, Link found blocks in all of the eight dungeons, usually arranged in patterns, with one of the blocks being movable. From then on, the block would be pushed out of the way for a treasure chest or two, as in the "Desert Block Maze" Heart Piece in  A Link to the Past. Later, the Cane of Somaria would come along in creating blocks for rooms without them, pots, or Armos Statues.
