Support Characters
Support characters are characters that appear during races that try to HELP you. Each does a different thing. So, here they are:
Lakitu
Everyone knows Lakitu! Well, here he is. He actually works for Bowser, but he's actually a traitor. Lakitu does lots of things; he gives you the Start Signal and when to go, he brings you back to the track if you fall off or into water, he brings you back to Earth if you crash into a Bowser Car, and he gets you out of a Hungry Luma's stomach if one eats you! You should really thank him. Oh, and he also tells you what lap you're on, accompanied by little tune.
Toadsworth
Jolly old bean, 'tis Toadsworth, the sly old dog! Blimey! Toadsworth is here to reprise his role from Mario Kart: Double Dash!! Except now, he drives the podiums in his mini pickup truck! Isn't that awesome?
Piantas
Piantas appear in multiple courses as the main members of the audience. They're cheering you on!
Nokis
Nokis appear in multiple courses as the other members of the audience. They're cheering you on!
Lubba
Lubba is the voice commentator of the game! You won't hear him talk, but you'll sometimes see him loitering around the tracks, watching the race! If, when you see him, you press Select, the race will pause and he'll give a description on the course. This description then becomes available in Records.
