Summons a controllable ghost that can perform various tasks depending on what it targets.

"Caaan do!"

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 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. BFFS! does not increase this damage.
- Doors: Opens the door, even if it is locked. Functions the same as Dad's Key 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 the Mysterious Door. However, it does work on doors leading to alternate path levels.
- Secret room entrances: Explodes, opening the entrance.
- Destructible obstacles, shopkeepers, machines, and beggars: Explodes and destroys them.
