These are my stage ideas for a Mario Party Island Tour stage.
Base Idea: It would be a medium stage, there would be dual long track on the top and bottom with two Banzai bill cannons. there would be small thick platform with a button. Landing on the button would switch the cannon the bullet bill would fire. There will be green spaces on the tracks that switch between Green and Banzai. Stepping on a banzai space would fire a banzai bill. The Banzai Bill would go fast and deal around 37%. It would knock anyone hit to the space that changes the position the Banzai fires.
