Hammer (Luigi's Mansion 3)

Hammers are ghosts in Luigi's Mansion 3. They are quite similar to Slammers from Luigi's Mansion: Dark Moon, as they are red, large, and beefy, and even have similar names and are shaped quite similarly. They have square heads and attack by charging toward Luigi or Gooigi and hammering the floor, hence "Hammer". Like Slammers, they tend to act more brawny than intelligent. Hammers have 200 HP. Hammers have two tails, allowing both Luigi and Gooigi to vacuum them at the same time. Whenever they charge, they will cover their eyes with their arms, rendering them immune to the flash bulb for the attack. When they are stunned using the Strobulb, they will barely move or take damage unless Luigi or Gooigi moves behind them while they are stunned and then suck them up.

The first Hammer in the game appears on the third floor, the Hotel Shops. It uses a water sprinkler above to melt Gooigi and speeds up the escalators.

Like Goobs, Hammers work lots of odd jobs at The Last Resort, but are easily angered.

The end of the game reveals the Hammers were being brainwashed by King Boo's crown gem, as they and the other ghosts quickly regain their senses and become friendly once the gem vanishes from Luigi's hands as they were about to attack him. Among the rest of the standard ghosts in the game, Hammers are seen working with the protagonists to rebuild the fallen hotel through a series of pictures throughout the closing credits, as well as the cinematic immediately preceding the credits sequence itself. The Hammer was also shown to be slightly dim-witted in his base personality, as when handed a helmet by Professor Gadd when preparing them to work on restoring the hotel, the Hammer mistook it for a snack and ate it, much to the other ghosts' embarrassment.
