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. Should Wario ground pound an Arrow Block, it will move downward.
