yes i beat the pit of 100 trials:
what you do is you have to reach the bottom(picking up items and gaining a couple lv ups)
when you reach the bottom,you have to do one last test:you have to beat the ultimate boss(i suggest being lv 35)
i'll point out his status:
HP:200
ATK:8
DEF:2
yea he's pretty d*** strong so bring some life shrooms and jelly ultras with you cause when he gets down to like half his health he will restore himself for 20 HP(i don't need to worry cause he was really easy for me)
after you beat him you get the "return postage badge"which when worn,monsters that tackle you(i.e.goombas,koopas,etc..)will take half the damage they give to you.
To all of those poor unlucky souls out there, this is for you:
