Speedy Spirit

Speedy Spirits are rare ghosts found by Luigi only in Luigi's Mansion.

Appearance
Speedy Spirits are pale blue and have a similar build to a Gold Ghost. Unlike others who attack Luigi, Speedy Spirits hide from him. If they are discovered by examining an object, they will panic and try to run off. Luigi must shine his light on it and immediately suck it up before it does. If Luigi manages to capture one of them, it will yield a large amount of treasure which always includes Coins but sometimes includes valuable treasures such as Gold bars and Stones. There are a total of fifteen Speedy Spirits in the Mansion. Gold Mice are similar treasure yielding Ghosts. They are easier to catch but harder to find than Speedy Spirits.

Story
Speedy Spirits are only found when a room is dark, so Luigi should search everything in a room carefully before turning on the lights. They are quite frustrating to bag, as they tend to phase through said bag. Also, the length of time they are stunned by the flashlight is the shortest of any ghost. Therefore, the best time to stun and capture one is immediately after uncovering it, before they have a chance to dart around the room. An interesting note about them is that unlike the Gold Mice, if Luigi uncovers a Speedy Spirit and fails to catch it, it will never come back, even after the blackout. Therefore the player will have to reload the game to try again, making it tedious to get them if not captured the first time around.
