Bum Bum is a 25 year old boom boom species. She doesn't fight for bowser, she will fight in self defense though. She has this little..."tick" where her butt gets bigger when her name is uttered ESPECIALLY when near pom pom. She has the powers of a boom boom and pom pom. Her weapon of choice, aside from her butt when it's big enough, are marbles (which can be enhances to be like a cannon ball in material).
