8-bit Toad
If you want even more Captain Toad: Treasure Tracker to play in each level once you've ran through the game, never fear, the 8-bit Toad minigame is here. On Wii U this was locked behind an amiibo, but now comes as standard. You can press ZR on the level select screen and jump into any level with a fun new game. Here, an 8-bit Toad sprite will be hidden in the level, and you simply need to seek him out, and tap him, either on the Switch screen or using the controller gyro functions. He's hidden well in most stages, so keep an eye out!
