The sounds of chirping birds, mooing cows, quacking ducks and of course the whistle of the train as it whooshes along blend together to add some quirky fun to every screen and puzzle.

Presentation-wise, the fonts are crisp, the menus easy to navigate and the overall theme is charming - adorable animals are everywhere in this game, and the Professor and his train are both cutesy enough. By its very nature this game is made to be picked up and put down at any time, so do yourself a favour: play it in short bursts instead of attempting to make it through everything all in one long session. Whether you're attempting to outdo your own score in a particular minigame, making your way through the quests and racking up trophies or hoping to score an A in Test Mode eventually, the game features so little plot and so much in the way of repetitive gameplay that extended play will bore you. The replay value in this game is all on you. Here you may choose any of the games available to you and have at 'em, either with a time limit (just like in the other modes, for that authentic race-against-the-clock feel) or without, where you just play until you get tired or stuck. If you're not happy with how well you're scoring in Test Mode, or if you're just in the mood to play a specific minigame with no quest strings attached, Practice Mode will help you to work out any kinks. There's no way to recall the results of prior tests except for your personal best, but the game will keep track of how far your brain has helped you travel overall. It's a little over 21 points to the kilometre in Test Mode so that the game can more easily give you a real-world example of how far you would've travelled every time you complete a test: 6,726 km, for instance, is apparently close to the distance between Tokyo, Japan and Mumbai, India. After completing them one by one, your individual scores are combined and you're awarded a letter grade and also told how far your brain power during that particular test has carried the train. In Test Mode, you're presented with five minigames at random, one from each category. To an adult, these quests seem as if they were merely tacked on in order to give you some kind of superficial purpose for continuing to play minigame after minigame, but younger children will probably get a kick out of the silliness involved. Upon completing a quest you're given a new piece of track to add to the map so that you can reach other animals and accept their quests as well the game will automatically choose the shortest route you're allowed to use according to the terms of the quest, so no worries about wasting time going the wrong way.

You may Reset or Skip any puzzle at any time without fear of penalty, but if you submit the wrong answer to a puzzle, you'll be docked points from your end score. You're awarded points based on how many puzzles you managed to get through, how quickly you completed them and also how many seconds you had left on the clock when you completed the last puzzle. How well you perform during a minigame determines how many points you earn as well as how far you travel around the tracks on the map. Sometimes the pointer gets hung up in parts of the maze, but there are no noticeable control issues otherwise. Most are controlled by pointing and clicking with the Wii Remote and the A Button, although a couple of minigames (involving moving an animal around to various points on the screen) allow you to use the D-Pad instead, and one game has you leading a creature through a maze with the pointer. In Quest Mode, all of the minigames are timed, and you must do your best to complete as many puzzles as you can before time runs out.
