How do you beat Bonetail in Paper Mario TTYD the easy way?

Answer 1

Materials(in the game)

Power Rushes (many as you can find)

Power Bounce (Blue shoe)

First, go down The Pit of 100 Trials (stay at level 99)

Second, Equip all your Power Rushes and your Power Bounce. Feel free to equip your Badges.

Third, Go down the pipe in level 99. You'll meet Bonetail (oldest brother of Hooktail and Gloomtail) and after the scene use your Power Bounce as many times as you can (it'll probably do 70 damage each time you bounce). After 200 damage (probably 3 times or more if you wish.)you've beat him and you can stop. You'll get a treasure of Return Postage (just like Zap Tap but weaker and uses more Badge points which is useless.)
