Bubbles is brilliant, and easily one of the best characters in the game because of the orange chap's special move.

When activated, your body expands greatly and you begin rolling down the hill like a huge boulder. You have control over your movement, though it can be tricky to control at times.

The pay off is huge if you can master this special, as it can be used in all sorts of offensive, defensive, and passive situations.

Anything you collide with is destroyed as you collide with it, including both obstacles and other karts. There are some tracks where you'll be so large that the move takes up the entire track, ensuring that anything infront of you is wiped out, and since you're temporarily invincible, you won't need to worry about obstacles.

Since your body becomes larger, you can use it to collect more Coins and Fruit than normal in Fruit Splat Challenges, and the damage it can do is perfect for Race Challenges and Champion Chases.

You're even given a dash more speed when you use it, and coupled with its ability to negate obstacles it can make Time Boom Challenges a doddle.

The only downside? It doesn't last as long as you'd like. It's a small price to pay.
