Captain Toad: Treasure Tracker

Playing as Captain Toad, you get to solve puzzles to save Toadette - who was abducted by a big bird. Later in the game, the roles are reversed. The Super Mario series Toad amiibo will unlock a bonus game on almost every course where the player has to find Pixel Toad. Any other amiibo will give the player a 1-Up Mushroom, or randomly two 1-Up Mushrooms.
