The Crazy Castle is a giant inflatable yellow castle located in the Wild West area of Witchyworld in Banjo-Tooie. To inflate the Crazy Castle, you must first go into the Pump Room where you split up Banjo and Kazooie and bring them to two switches. Once you've done that, the castle will start inflating. There are two challenges you can do inside the Crazy Castle: the Hoop Hurry Challenge (can only be done with Kazooie) and the Balloon Burst Challenge.
Hoop Hurry Challenge
Kazooie will have 60 seconds in which to score 30 points by running through different size and colored hoops. Red hoops are the largest and are worth only one point. Green hoops are medium-sized and are worth two points. Blue hoops are the smallest and are worth three points. Kazooie may or may not use the Running Shoes located in the middle of the room.
Balloon Burst Challenge
Banjo and Kazooie will have 60 seconds in which to score 50 points by hitting balloons while flying in the air. Blue balloons are worth 3 points, green balloons are 2 points, and red balloons are 1 point. Kazooie may or may not use the Running Shoes located in the middle of the room. Note: You need to be able to shoot eggs while flying first. You have an infinite amount of eggs for this challenge.
If Banjo and Kazooie score 50 points, they are awarded with a Jiggy. In the Xbox Live Arcade version, if Banjo and Kazooie score 60 points, they are awarded with an achievement.
