- "Now that these ghosts have been augmented by the crystals, capturing them is even trickier. It's best to wait until they show themselves to stun them."
- ― Ghost Container Description, Luigi's Mansion: Dark Moon
Strong Hiders are stronger variants of Hiders found in Luigi's Mansion: Dark Moon. They resemble normal Hiders, but have the stony texture on them, as of other strong ghosts. They behave just like Hiders, however. They are a bit more difficult to find and they have 75 HP, instead of 15. Strong Hiders only appear in the Treacherous Mansion.
