Ghost Combs are collectibles found in Luigi's Mansion 4: Haunted Dreams, Luigi's Mansion 5: Curse of the Mansion, and Luigi's Mansion 6: U Are Doomed!!. They are the most common items between all three games. Luigi can earn an extra life for every 50 Ghost Combs collected (every 100 in Curse of the Mansion and U Are Doomed!!). Unlike Coins, Ghost Combs do not replenish the character's health. Should Mario or Luigi lose a life, they will lose their coins, however, their amount of Ghost Combs stays the same. Ghost Combs are kept track of by a Ghost Comb counter. Ghost Combs are mostly found by sucking up an enemy instead of stepping on them, as stepping on them produces a coin.
