how wide of a variety of stickers are there at world 2? if you can't figure out which to use, you must not have beaten any paper mario game unaided, since they all need you to solve a puzzle here and there
e: looked it up, you don't even need the special sticker, you're just bad
Excuse me. I did look it up and the sticker you use you dont even get in that zone. No other Paper Mario game REQUIRES a special item, an un-hinted item by the way, to beat any boss. I dont think you have played any other Paper Mario game
Also, you CANNOT beat that boss without that sticker.
The boss does 4 damage each hit and alternates each turn: 2 hits, 3 hits, 4 hits, poison blast. Do thats 8 damage, then 12 damage, then 16 damage. If you are hit with the poison (which does 7 I think), you cannot hit the boss with attacks while it attacks you. The boss has 300 health and your attacks are reduced in damage by 75% against it. That means your normal jump does a maximum of 4 damage.
The sticker negates its defense, poisons it for 30 damage, and always makes it miss for three turns. Now, tell me you dont need that sticker.
Doesn't sound like you've played this game.
And for the record, I did beat the boss.
So forget you.
