Secret rooms. You can't open them without a certain kind of sticker, which is only sold in one particular store as far as I know.Anyone know what those door outlines are for?
Those are rooms that have 'things'. The items that can be converted into stickers. You can find the doors in World 3, in the world that has shops in it.Anyone know what those door outlines are for?
You need a door sticker to open these. Usually contain sticker boxes,hearts,coins, some might have warp tunnels. I still was unable to find a list of how much damage each sticker produces lol.
