To get a special move, simply collect 5 stars that are scattered around the track, then press to use it. Alex’s special move is Mane Man – Alex causes other races to spin out by pouncing on their karts. This one is slightly harder to hit 3 people with than some others, how his star move works is you press and he stands on top of his kart and when other racers are in range you press again and he will jump into that kart and make it spin out. So the best thing to do is drop back into a lower position and wait until you are near a load of them and try it then. It can be unlocked in circuit mode, quick race or the star collectible race challenge.
