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.
Easy Charaboms
In a two player battle, you normally would lose your Charabom if you lost. However, turn off the power immediately before losing. Your opponent will get a free Charabom and you will not lose one. If done purposely, the person who wanted to give someone a copy of their Charabom would purposely lose, turning off before the final blow.
