Player Probe

The Player Probe is an item added by Actually Additions. Right-clicking a player with it will store the player's data in the Player Probe. Then, right-clicking a Player Interface will change the player that it interacts with to the new player selected, and then the data of the selected player will be cleared in the Player Probe. If the selected player sneaks while their data is in the Player Probe, the selected player will be notified in chat.
