Creeper

Creepers are gooey, gelatinous ghosts that appear in Luigi's Mansion: Dark Moon. They have infinite HP; simply pulling in the opposite direction cannot defeat them, so the player must charge up the Power Gauge and press to unleash a Power Surge.

Appearance
When Creepers are first encountered, they appear as large purple puddles. When fully revealed, they are purple beings with white eyes and always-smiling mouths with tiny upper and lower fangs, two arms, and a puddle underneath them.

Abilities
Creepers can turn into puddles making them invincible. Once the Dark-Light is shone on them or if the Poltergust 5000 sucks them long enough, they reveal themselves. If Luigi walks over them when they are in puddle form, they rise up and imprison him in their bodies, causing damage. They can also break into smaller versions of themselves. Once smaller, they can be sucked up without a power surge. In the main story, Creepers can even hang from ceilings and drop on Luigi if he walks underneath them.

Ghost Container Description
''These gooey ghosts just love to cuddle, and they'll never want to let you go. But after the Dark Moon broke apart, they forgot about the cuddling part. Watch out for them on floors and ceilings!''

Trivia

 * Creepers are the only ghosts not introduced through a cutscene, and also don't seem to interest Professor E. Gadd as much as the other ghosts.
 * Creepers are the only common ghost to lack a Strong form.
 * In ScareScraper, if a normal Creeper summoned by a boss Creeper attacks, and Luigi frees himself from it, it will disappear instead of breaking into smaller ones.
