Giddy Sky

Giddy Sky is the seventh world in the game Super Princess Peach, and, as its name implies, takes place in the sky. The boss of this world is Kamek, who transforms himself into Giant Kamek. He must be defeated in order to rescue Luigi. The main inhabitants, such as Lakitus, Paragoombas, Amazing Flyin' Hammer Brothers, Paratroopas, and their corresponding emotional forms, are capable of flight unless Peach jumps on them. There are also hot air balloons that are described as strange devices by the message blocks. Rage is required to make them go up, and there are usually Vibe Crystals along the way.

Trivia

 * Unlike in most Mario games, Princess Peach cannot jump through the clouds unless they're weakening.
