The short answer
A Grand Prix is the big race at the end of every world in Animal Loop: all nine of the world's tracks, raced back to back at one speed you pick, against that world's rival animal. Beat the rival and they join your roster. Your best total time stays on the Grand Prix card, and your Game Center friends' times show up next to it.
How a Grand Prix works
Find it under the tracks
Every world has nine tracks, shown as a grid of their outlines. The Grand Prix sits right under the grid. Its card shows all nine track shapes in race order and your best total time, so you know exactly what you're signing up for.

Pick your speed and face the rival
You race the whole Grand Prix at one speed you pick. Before it starts, the doors close on the world's rival animal, on top, and you, below, with both of your best times.

Race all nine tracks back to back
The Grand Prix runs every track in the world, one after another, with a lights-out transition between legs. Your times add up to one total. Tap to turn, stay off the walls and keep your hearts.
Beat the rival, win the racer
Beat the world's rival and they join your roster, so you can race as them on any track. Then come back to beat your own best total, and your friends'.

How many Grand Prix are there in Animal Loop?
Three, one for each world: Dune Flats, Coral Shallows and Fern Hollow. Each one races all nine of that world's tracks.

Can I race my friends in a Grand Prix?

Any tips for winning a Grand Prix?
Learn each track on its own first: the stars on each track card show what you've mastered. Then race the Grand Prix at a slower speed, and turn it up once you know all nine tracks by heart.
