Two bronze bookends, one a lion and one an eagle, which are viewed as a reference to "Dr. Jekyll and Mr. Hyde". If the heads are transposed and 2 people touch one of the bookends at the same time, it's possible for those people to switch minds. However, it appears the mind switch doesn't happen immediately and wearing gloves doesn't negate the effect. The minds can be switched back by putting the lion's head on the lion's body and the eagle's head on the eagle's body. If the bookends are separated, then when one is placed on a flat surface its eyes will glow and it will rotate to point in the direction of the other. The bodies of the two parties who switched minds will eventually merge, so one second you'll be talking to Bob, but then he disappears and Jack is standing in his place. Howeve
