Chauncey

Chauncey, the Spoiled Baby is the third Portrait Ghost Luigi encounters and is the first boss in Luigi's Mansion. Chauncey is the son of Neville and Lydia and the brother of Henry and Orville.

When Luigi first found Chauncey in the Nursery in the first area he was sleeping. In order to wake him, Luigi used his trusty vacuum to rock the rocking horse nearby. Chauncey then tried to "play" with Luigi by throwing balls and teddy bears at the green plumber. In an attempt to fight back, Luigi used his Poltergust to capture a ball and throw it back at Chauncey. But, this turned out to be a bad move, as Chauncey became upset over his "owie" and ordered Luigi to become tiny!

The green-capped hero landed on Chauncey's crib, miniature-sized, now staring at a huge Spoiled Baby! Soon, Chauncey directed three gigantic rocking horses at the plumber, one by one, causing five HP if damage for each hit. Then large balls rained down onto the crib, causing seven HP damage for each hit. But, one ball remained after this downpour, and Luigi took the opportunity to suck the ball and redirect to back to Chauncey, now making him vulnerable. But, with the plumber still small, Luigi would not capture Chauncey in one try. After his failure, the baby would romp around the crib, damaging Luigi ten HP if he was caught in his path. It would take three or four tries to capture the Spoiled Baby, after which Luigi would earn a special key, breaking the force field on the first floor so the plumber could explore it in his search for Mario.

Trivia

 * Even in Hidden Mansion mode, it is impossible to capture Chauncey in one try; the game forces Luigi to let go at 20 HP.
