Ghost's heart

A Ghost Heart is a heart in the game Luigi's Mansion. When the player flashes the light on a ghost, it will be stunned and will show its heart for some time. Then the player can suck the ghost up in the Poltergust 3000, however it can only be done when its heart is showing.

Portrait Ghosts are harder to catch as they won't show their hearts so easily. The player needs to find their weakness and then the player can shine the light on the ghost and suck them into the vacuum. Though the player needs only 18 out of 23 portrait ghosts to save Mario, while the other five are optional but they will give the player alot of treasure if players catch them in the Poltergust 3000.
