Creeper

Creeper are enemies that appear in Luigi's Mansion: Dark Moon. Like Sneakers, they are first seen in the manison Haunted Towers and appear in every other mansion afterwards. They are one of the toughest enemies to deal with in the game.

Appearance
Creepers are mainly purple slim ghosts. Their size varies depending on how much Luigi has attempted to vacuum up.

Battle
Creepers actually stay on the ground as purple puddles waiting for Luigi to get close. When Luigi gets close, they spring up and, if successful, trap Luigi in their bodies dealing multiple damage until he breaks free. They can also split up into smaller Gobbers making them even tougher to catch.

Tips
The easiest and safest way to capture a Creeper is by using the Dark-Light Device. Once Luigi shines the Dark-Light Device on a Creeper puddle, it will quickly spring up where Luigi can Strobulb and proceed to capture the Creeper into the Poltergust 5000. Luigi needs to charge the Poltergust 5000 to the second level in order to fully capture Creepers.
