Greenie

Greenies are the first ghosts that Luigi comes across in Luigi's Mansion: Dark Moon. The Greenies were originally helping Professor Elvin Gadd, but when the Dark Moon shattered, they turned against him. Greenies usually appear in groups ranging from 2-4, and have 10 HP. There is also a Gold form that expels large amounts of treasure when captured.

Abilities
Greenies attack Luigi with a short range punch, similar to Gold Ghosts, but are able to equip themselves with various objects to fight against Luigi. This is done by equipping themselves with sunglasses to block the Strobulb's effect or using a rolling pin and pan lid to do more damage and block the Strobulb's effect. This forces Luigi to remove the equipment or find an opportunity to use the Strobulb. Greenies are also capable of disguising themselves as other creatures like mummies. They also change up their attacks sometimes. In the Old Clockworks, several Greenies are found creating mini-tornadoes to drag Luigi in and do damage. They also develop a shield which gives them infinite HP that can be reduced to 10 HP by waiting for the Power Gauge to build up completely, then pressing "A".

''They like to tinker with things they shouldn't and wield everyday objects as weapons. First, find a way to disarm them, then stun them with your flashlight when the time is right.''
