Yoshi's Rainbow is the eleventh Event Match in Super Smash Bros. Brawl. You play as Ice Climbers on Rainbow Cruise and must KO the Yoshis in order that they appear. The event is a failure if you KO the wrong Yoshi. So one wrong Yoshi and the event ends in a failure. On harder difficulties, the Yoshis know when they are the target, and they try to put as much distance between themselves and the player as possible. This makes it very difficult to kill them, as they're constantly jumping around the stage trying to avoid you. Even if you manage to get a good hit in, they'll likely recover several times before you land a killing blow. To make matters worse, oftentimes the wrong Yoshi will fall to his death, resulting in a failure even though you didn't KO him. It can be one of the more frustrating events in the game.
- The aim of this event is the same as the bonus, Yoshi Rainbow, in Super Smash Bros., which is earned by knocking out the Yoshi Team in the order in which they appear.
