How do you beat the last boss world 6 on new super Mario bros Nintendo DS?

Answer 1

To defeat Monty Mole, you have to just jump on him.

1) When he's at his 1 level tank, wait 'till he jumps up to throw a bob-om at you and jump on his head. Then duck, because he's going to go crazy with the Bullet Bill's.

2) When he's at his 2 level tank, you should still be able to jump on him while avoiding the Bullet Bill's. Again, duck because he'll be shooting at you.

3) Here's where it gets tricky. When he's at his 3 level tank, you have 3 options: (1) Wait until the middle or bottom part of the tank body are facing you, and jump from them onto his head.

(2) Wait until he shoots a Bullet Bill from the bottom or the middle part of the tank body and, if you press the jump button just as you land on it, you will do a large jump, and so be able to land on his head.

(3) Wait until he throws a bob-om, pick it up and throw it at him.

All done!
