Paper Mario: The Thousand-Year Door Tips

pit of 100 trials
If you want to go to the pit of 100 trials, you have to be prepared. First off, you should be at least level 30, second, you need at least 3 jelly-ultras[can be made by jammin' jelly+ultra shroom, third, bonetail is really hard, 200hp, so get all your partners powered up twice[after getting the up arrow],and fourth have a good time! Hope this is helpful!

note:the up arrow can be reached in Hooktail castle, once you have Bobbery, then you go back to where you were cursed, go back to the trapped room[the room to the right] and you can explode the wall.
