Pressing the X button shows the map on the screen.

Our research indicates that the mid-battle stage map has changed a bit. Apparently Inklings can press the X Button to view the map at any time during a battle. Once the map is open, they can then press the directional buttons and the A Button to Super Jump to a teammate. Each teammate is assigned to a different directional button, as is the spawn point. The map also features a cursor that can be moved by tilting the controller.
