World 4-1 (Mario Party: Star Rush)
World 4-1 is the first board of World 4 in Mario Party: Star Rush. As all boards in World 4, it takes place in a lava-filled castle, presumably owned by Bowser indicated by the large statue of him in the background. The main feature of this board is the rising lava. Every now and then, the ground rumbles to indicate that the lava will rise the next turn. When the next turn occurs, the lava rises, making the lowest level of the board inaccessible and burning any players who have not retreated to higher ground, causing them to transport elsewhere on the board, losing 2 coins in the process. The board contains three Lakitu spaces and one Shy Guy Shop, making it the only first board to have these board features. The board features three boss battles, a number shared with all first boards of each world barring World 0.
A board detail includes a statue molded after a Mechakoopa, found on the upper right area of the board.
