Showtime

Showtime (parsed as Show Time in the British English version) is the boss mission in Old Clockworks from Luigi's Mansion: Dark Moon. Here, Luigi fights the Overset Possessor who possesses the belfry clock. Luigi can earn the Dark Moon piece when the Overset Possessor is defeated.

Overview
This mission starts off with Professor E. Gadd and Luigi inspecting an image the Toad assistant brought back from the preceding mission. It reveals the Overset Possessor, ghosts such as Greenies, Boos carrying a portrait in a sack and King Boo's shadow. After Luigi is done inspecting the picture, E. Gadd pixelizes Luigi to the Clock Tower Gate.

In the Clock Tower Gate, Luigi should inspect a crack on the wall to reveal the numbers necessary to open the Clock Tower Gate: 7:30. Luigi should then insert the rotor and the clock hands on the gate, then turn the rotor to make the time match 7:30. This opens the door to Movements. If Luigi tries to leave the Clock Tower Gate at all, E. Gadd will contact him, demanding him to get to the top. In Movements, Luigi should spin the rotors on the wall to take him up Movements, which then lead him into the Belfry. Luigi should walk through the Belfry and into the ladder, where a springboard flings him into the Belfry Clock. After Luigi has fought the four hordes of ghosts, a clock hand will start to glow red and moves in circles, Luigi has to go to dodge the clock hand glowing by standing in a safe place. This is where the Overset Possessor is fought. In this boss fight, Luigi mostly fights off hordes of ghosts and other enemies at each number:


 * 1: One Greenie.
 * 2: Three Greenies.
 * 3: Five Greenies.
 * 4: Two Slammers.
 * Overset Possessor's first stage.
 * 5: Nine Beetles.
 * 6: Three Sneakers.
 * 7: Three Greenies with mallets and shields.
 * 8: Three Mummies.
 * Overset Possessor's second stage.
 * 9: Fourteen Beetles; burning clock hands.
 * 10: Five Creepers; burning clock hands.
 * 11: Eleven Robombs
 * 12: One Greenie, one Robomb, one Sneaker, five Beetles, one Slammer, one armed Greenie; burning clock hands.
 * Overset Possessor's third stage.

Once Luigi catches the Possessor, the clock gets set back to 12:00 and the fourth Dark Moon piece flies out of the Poltergust 5000. E. Gadd calls Luigi after that and brings him back to the Bunker but not before a giant cuckoo bird from the clock startles him and chimes so loud that he has to cover his ears. As soon as Luigi lands in the Bunker, he pulls out the Dark Moon piece to clean it, which causes more fog to lift up around the mountains of Evershade Valley revealing the Secret Mine.
