Sometimes your Ninja might do something silly and get himself stuck. If this happens, you can help your Ninja out by fully closing the app. 

To fully close an app:

  1. Open your Android settings menu
  2. Select the Applications or Apps option. The exact name of this option will depend on your device
  3. Tap Manage Applications.
  4. Select Running at the top of your Manage Applications window.
  5. View your list of running applications.
  6. Select Clumsy Ninja from the list and tap the Stop or Force Stop button to fully close the app. Again, the exactly name of the button will depend on your device.
