Allows the user to read the mind of the animal wearing Coco's Fez while wearing Mr. Mental's. Coco's fez acts like a transmitter and Mr. Mental's fez acts like a reciever. If one of the hats is taken off while the other is on it causes the brain of the wearer to short circuit. When the hats are taken off at the same time this effect is avoided, but residual effects cause the animal to develop a bond to the human.
In his performances, Mr. Mental would pretend he could talk to the monkey, Coco, but really he was reading her mind. He had some good shows until a spectator took off Coco's fez, declaring they were running a con somehow, and Mr. Mental spent the rest of his life in a mental hospital after losing his mind and attacking the audience.
