Bubbler is a real sourpuss, and like all the bosses, likes to use every advantage he has to win. He'll drop mines in your path as he races ahead. Therefore, it's best to hang far enough back that you can see the mines and avoid them, but close enough to stay in the race. Load up on the Red Balloons, then sink Bubbler with a volley of missiles as you pass him near the finish line. The first time you race Bubbler, he'll drop mines; after you beat him once, he'll drop bubbles.
