Lightning Serve

Hold Up+B and press A to start the serve, then hold Down+B and press A when the ball turns red to finish the serve.

The serve will look like a normal underhand serve until it reaches the opponents side, then zig-zag unexpectedly catching them off guard. This can only be used once per set.
