Luigi's Mansion Help!

[Beardo]

I've played this game through 2 times, all the way up until the Bowser/King Boo final boss fight. I can never seem to beat him! Please, someone, help! Every time I get close with a bomb, he starts to blow fire. I just need to know if he's gonna blow fire or try and suck me up.

Whenever Bowser throws the spike bombs, suck them in.
When he starts to charge at you, release the spike bomb, and suck in King Boo while avoiding Bowser's icicle attack (It hurts BTW).

I finally beat it! I thought you had to wait intil he was sucking in air to release the bomb, but I guess not! Onto the secret mansion I guess
