I hope someday I'll be able to figure you how you got your score of 02:38.58 . Currently the best run I've done is 02:55.71 . Oh well, maybe I'll be able to figure out the secret someday. :)

I won't give away my whole secret, but it may help to know that my 100% route hits Spookyland first, then Carnival Land, then detouring through the middle for the last boat before Expedition Land and doubling back for the exit. Be sure to use roll jumps when possible, since they're the fastest form of movement in the game. Good luck!
