Mr. ME!

Mr. ME! is an unlockable activated item added in Booster Pack #3.

Effects

 * Summons a ghost near Isaac that will follow him around, and summons a controllable blue crosshair. After a few seconds, the crosshair disappears, and the ghost will act depending on what the crosshair was targeting:
 * Items, pickups, trinkets, brown/red/spiked/mega chests: Brings it to Isaac. Works in shops, devil deals, and black markets as well, making them effectively free. Stealing an item has a 50% chance to fail. If that happens, a buzzer sound will play out and the ghost will disappear without doing anything.
 * Golden/eternal/stone chests: Opens the chest for free.
 * Buttons: Presses the button.
 * Enemies: Attacks the enemy until it dies or can no longer be targeted due to a form change or similar cause. The ghost does 3 damage per tick, for 9 damage per second. does not increase this damage.
 * Doors: Opens the door, even if it is locked. Functions the same as when being used in this way. This includes the door to Mega Satan, exiting Hush's room, and exiting Boss Rush.
 * This does not work on A Strange Door. However, it does work on doors leading to alternate path levels.
 * This does not work on the hidden closet in to unlock the tainted characters.
 * Secret room entrances: Explodes, opening the entrance.
 * Destructible obstacles, shopkeepers, machines, and beggars: Explodes and destroys them.

Interactions

 * May sometimes glitch pedestal items, resulting in Isaac being unable to pick them up without leaving and re-entering the room. Otherwise has no effect.
 * If Mr. ME! successfully stole a consumable from the shop, there is a chance he will drop a sack instead.

Trivia
