The Mind Control Device is a gun that shares its art with the Shrink Ray. Although it looks the same as the Shrink Ray, it has the same effect as a Cupid Bow, that is, to make any creature more friendly. This can be used for many things, such as riding powerful creatures that are normally hostile, like a Dragon, or stopping hostile characters from killing you. Although it makes Edison have the smiley face icon, he will still try to eat you. Same for a Pyromaniac, who will keep trying to kill you.
