stages

Peach's Castle-- Although it doesn't look like a castle, it is suppossed to be one. There is a bumper constantly floating above the stage. The platform on the bottom is always moving left and right, so it could help you, or really hurt you. The two triangle blocks on the sides often stop enemies from flying too far, so hit 'em when they come back!
Congo Jungle-- One of the smaller levels. There are 2 rotating platforms in the center. A barrel underneath the level could save your life.
Hyrule Castle-- Among the largest levels, Hyrule Castle is relatively flat. Three platforms in the middle and one tower on the right are the only platforms. Occasionaly a tornado will whip up and move about its area of the level
Planet Zebes-- One of the most excitng levels of all, it is also the most dangerous. Acid will churn up regularly, and it does a lot of damage.
Mushroom Kingdom-- The only level that you can't fall off the side of. Standing on the platforms in the middle will make the other one fall. Hit the POW box that appears to do 20% damage to anyone touching the ground. Press down while on one of the Warp Pipes to go to the other side of the arena. You might get put out in the middle of the stage though. Watch out for Pirahna Flowers in the warp pipes.
Yoshi's Island-- A simple level with clouds on the sides. Stand on one too long and it will disapear. It is the only stage where eggs will appear without a Chansey in a PokeBall.
Dream Land-- Probably the simplest level of all. The tree in the backround will blow at you occasionally. If you aren't paying attention, you might get blown off.
Sector Z-- The longest stage. Arwings often are flying by, and will shoot at you, sending you flying.
Saffron City-- One of the harder levels. When the door on the main area of the stage opens, watch out or a Pokemon will attack you. Platforms are moving up and down on the left. Click here for a list of the Pokemon that appear in Saffron City.
