if you have all the keys, all the trophies, completed all challenges, and beaten wizpig, go to the billboard near the light house and honk your horn. you'll go to some future place that has the t.t. door. complete all challenges in the future place to fight wizpig a second time! this time he rides a rocket and you ride a plane and there are lots of obstacles. use pipsi when racing the final wizpig.
another thing to do after collecting all the trophies is to look at all the frogs in the main area. look for one frog with a rooster hat. squash him and you'll unlock drumstick! drumstick has an excellent top speed but really stinks in handling.
another thing to do is time trials in tracks mode. if you get a super good time you'll race a t.t. ghost. if you beat the t.t. ghost in all the tracks you'll earn t.t. as a character! t.t. has a super ultra mega awesome top speed but has pretty bad handling.
I heard rumors that you can unlock wizpig and taj but I really don't think you can.

Go to billboard near the light house and honk ur horn at it then the light house will turn into a space ship then u can play the 5th lvls after that go f*ck urself

well then u can race his ghost and then if u bet his time trial mode u will get to have the real t.t as an option in ur player chosing place!!!


The greatest of luck with that and a little tip hit every zipper that u can find!!!

BITCH
