Ok I know this is kinda picky but how do I unlock all players what lvl..

To beat Story mode 1 is the same to unlocking Story mode 2. Story Mode 2 is the same except the tracks and bosses (not island) is all in reverse, but you still get all the extra things like Story mode 1 with the balloons and stuff.

To beat it, you must have played and beaten the Bosses twice (after the balloon thing on the track), played the cups and beaten it with you first. After you beat all the bosses, you should end up getting all pieces of Wizpig's face on the statue in the main area and open up a cave. Go inside and beat Wizpig. (Make sure when versing him, you got a good person with good handling capability and you use every boost on the track. You may also need an upgrade on the Kart to help you beat him because it was the only way I beaten him)

After you beat wizpig, and you beaten all 4 cups, you should unlock the 5th world, Future Fun Land. Beat that and wizpig again in Future Fun Land. (Its a lot harder on these tracks and Wizpig is a lot tougher than what you were up against before).

Oh, I forgot the other stuff. Each character has it's own special way to be unlocked.

Drumstick (Chicken Guy): Go left of the wizpig statue and their should be a pond up on a platform. Get a frog and try throwing it at the pond at the top using your stylus. It is hard, but once it's done the frog should somehow transform with some red thing on his head like a chicken and once you squash with your kart or whatever vechile you used, you'll end up getting drumstick.

Taj (Elephant Gypsie Guy): Successfully complete Story Mode 1 with 47 Balloons. There is other balloons than the ones recieved from the tracks after beating the balloon races and Taj's challenges, hidden around the Island.

Wizpig (Pig Guy): Successfully do the same with Taj's way, except with Story Mode 2. Not sure if you had to do the same with collecting the balloons. But his stats are the same as Taj and really bad too.

T.T. (Time guy): Get all of the T.T Amulet (which I think you must also do before going to beat Wizpig for the final time) and Beat him in time trial mode. You can choose whether to have him on ghost or not, but you must have him on ghost in order to beat him and a clock symbol appears near the time when beaten I think. He's also the best good racer to have.

Im not sure whose 2nd best unlockable player, but I know the Tiger is used a lot and the turtle guy is good with the plane. (forgot names).
