Maiamai

These creatures are the children of Mother Maiamai, lost and scattered across the lands of Hyrule and Lorule. When Link first meets Mother Maiamai, she pleas for the hero to collect her children and return them, promising rewards in exchange. For every ten lost Maiamais Link finds, Mother Maiamai will upgrade one of his items (provided he owns the weapon and is not merely renting). In total, one hundred lost Maiamais can be found in the overworlds of A Link Between Worlds.

Collection
Maiamais are littered across the land, requiring a variety of maneuvers to capture. Such as using the Pegasus Boots, using the Torndao and Sand Rods, discovering them underneath Rocks and Grass, and by transforming into a painting behind them on walls.
