The bite-sized Captain Toad stages in Super Mario 3D World were a wonderful side dish, offering a very different type of challenge from the rest of the game. Little did we know at the time that the compact, puzzle-like levels would eventually find new life in a full-fledged game, Captain Toad: Treasure Tracker. Now, Captain Toad and Toadette, his partner in plunder, have hit the road on a quest of their own, and it's one of the most charming and enjoyable games to grace the Wii U. The two tiny explorers squawk and trot to all corners of the Mushroom Kingdom in search of golden treasure, and occasionally to rescue each other from danger. While it has a gleeful exterior, Captain Toad: Treasure Tracker's also a deceptively challenging romp, especially if you attempt to uncover all of the game's hidden items.
