New Super Mario Brothers DS Walkthrough Part 17

Part 17 of my New Super Mario Brothers DS Walkthrough. Mario continues on defeating more of Bower's helpers. In this part I do 3-B, 3-C, World 3 Castle, and defeat two evil big fish. In my next part I do World 4 AND I do it with Luigi! How to unlock Luigi is when you turn on your DS it goes to the logo that states: New Super Mario Brothers. Click ''Mario Game'' and then press R and L button on the back of your DS while pressing your file. You do not need to beat the game to do this. You will know it has worked when Luigi says: ''Luigi''. I think he should say more than just ''Luigi''. But that's just me. Remember to comment, rate, and subscribe! Thank you and enjoy many more of my videos! Bye!
