On this stage, mine carts sometimes appear. They start moving when someone gets inside, or travel on their own after a while. Try not to get run over!
When treasure chests appear on this stage, break them to get items! Some chests explode, though, so it might be safer to use projectiles.
The burning red Danger Zones are as dangerous as their name implies. Touch them with more than 100% damage, and you’re instantly KO’d.
