The SEGA plastic bags that are given out to people for playing the UFO Catcher machine features a Morse code message on it. When translated, it reads "UFO Catcher is not a vending machine." This message was added by the bag's graphic designer and means that because a player may insert money into it, it doesn't necessarily mean that they'll receive a prize. The bags have been in use since 2014 and the message's meaning was confirmed by SEGA on their official Twitter account.
