Strong Greenies are a variation of Greenies in Luigi's Mansion: Dark Moon that have been powered up by a special crystal from the mines. Their first appearance in the Dark Moon Quest mode is in the fourth world of the game, Secret Mine. Strong Greenies have 50 HP. Just as normal Greenies, they can equip objects and use them to attack. Unlike regular Greenies, however, they are covered in Paranormal Chains, giving them a cracked appearance. Just as regular Greenies, they come in groups. Luigi can use 
to dodge the other's attack while sucking one up. Strong Greenies escape from their crystals by punching through them, almost breaking the crystal.
In ScareScraper, Strong Greenies are usually found accompanying boss ghosts such as The Brain. The sub-boss from the Secret Mine has 100HP.
Ghost Container description
The Crystals of the mine have really changed these charming fellows. They're now much stronger and more able to get into shenanigans. Don't let them get equipped!
