Yeah, the cataquack.
The level of detail on each character is amazing, considering that there's 16+ different characters on screen at any given time, all animating differently yet amazingly smoothly. Looks like you can still fall off the track, though (2nd movie, yoshi tongue-attacks mario/luigi); hopefully it doesn't make you automatically lose a race like it did in the previous 2 mario kart games (automatically lose by giving you a huge delay time with no realistic way of making up the time).
