Stamp Patch

Stamp Patches are items found in Yoshi's Woolly World. They replace the Red Coins found in the previous Yoshi games.

Each level in Yoshi's World World contains 20 Stamp Patches, and collecting a certain number of Stamp Patches unlocks new stamps that the player could use in Miiverse. A total of 1,100 Stamp Patches appear in the game.

Stamp Patches do not reappear in Poochy & Yoshi's Woolly World, and they are replaced by Pencil Patches.

According to the game's text archive, Stamp Patches were originally known as Mii Beads and were pink patches with a Mii face on it.
