Bomberman Max Advance: Red Version

Bomb shield:
When holding Invisible Vest, set a bomb and just as it explodes rapidly press A repeatedly. This will protect you. Be careful not to blow yourself up after the Vest wears off.

Charabom that makes you very powerful:
In the Garden stage, get a Dorako and Elephan. Fuse them to make Elefandon, a Charabom that gives you the maximum amount of bombs and full power.
