A bead jar is a block that appears throughout Yoshi's Woolly World and Poochy & Yoshi's Woolly World, appearing infrequently throughout a handful of levels. When hit from below, it produces several beads from the top. After being hit a total of six times, the block produces one final bead that produces a Stamp Patch or Pencil Patch. The block's design resembles that of a jam jar with a flip-top lid.
