Regen Goob

Regen Goobs are rare ghosts in Luigi's Mansion 3. They are a rare variety of Goobs which appear in ScareScraper mode. They have 250 HP, more than double that of a regular Goob's. They are defeated the same way as normal Goobs. If released before defeated, however, they begin to quickly restore or regenerate HP, hence Regen.

Regen Hammers, a rare variety of Hammers, and Regen Slinkers, a rare variety of Slinkers, also appear in the game.
