Arrow Blocks are gray, metal blocks found inside trapdoor sub-levels in the game Wario World. The Arrow Block looks like a gray block with four red arrows pointing in the four cardinal directions on each side. If Wario punches the block, it will go sailing in a straight line until it hits a wall causing it to stop; if it hits another Arrow Block, that block starts to move instead, potentially resulting in a chain reaction of multiple blocks. Arrow Blocks are generally used as platforms to help Wario reach previously inaccessible ledges containing red diamonds and Gold Statue pieces.
