you will get 1000 pts each lap you do
onto track below and you will see yellow thief in front of you he will come past you as you get closer to him
try to flame him to make him reappear if you dont get him press L1L2r1r2 all at once [also this makes sparx point to treasure]to get red thief follow right track till you get to hole in wall on left hand side in between bit where you have to jump accross go in it and up whirly thing you should land on tower and can see red thief on tower below glide to tower landing next to thief and flame him ,hope it all helps
