Shy Guy Ghosts are undead Shy Guys that first appear in the game Luigi's Mansion. They can be red, yellow, green, purple, pink, white or orange with Shy Guy masks and are equipped with pitchforks resembling the one carried by Beezos from Super Mario Bros. 2 and the non-Mario game Yume Kojo: Doki Doki Panic. When Luigi uses the vacuum on them the masks come off revealing two yellow eyes in a dark void. Luigi can only suck up the ghosts once their mask has been removed. Shy Guy Ghosts have 20 HP, similar to Purple Punchers and a few Grabbing Ghosts.

Shy Guy Ghosts were originally planned to have blue and turquoise color swaps, which were later scrapped for unknown reasons.
