Peach's Castle is an unlockable stage from Jake's Super Smash Bros., hailing from the Super Mario universe. The stage is a medium stage, with a six player maximum. The fight takes place atop the roof of Princess Peach's castle. The stage acts as the home stage of two of the Super Mario princesses: Peach and Daisy.
The roof serves as the setting of the stage, which is primarily flat in appearance. A large, triangular tower protrudes from the centre of the stage, reaching up almost to the the top of the screen.
The roof is a basic stage, with the sole gimmick being the tower in the centre of the stage. The roof reaches almost to both ends of the screen, with the platform having angled edges that reach almost to the sides of the screen.
Princess Peach's Castle has appeared in a multitude of different games, many of which having different designs. The castle first appeared under the name of "Mushroom Castle" in Super Mario RPG: Legend of the Seven Stars. It made its first prominent appearance in Super Mario 64, where it served as the setting of the game, and takes its appearance from this game in Super Smash Bros..
The castle's appearance is almost identical to its appearance in Super Mario 64, down to the green Yoshi that appears in the background of the stage.
