Luigi's Mansion 2 wouldn't be the same without the Poltergust 5000, which is why the mustachio'd man must obtain it right at the start of the game. However, even after E. Gadd hands the Poltergust to Luigi, gamers will notice something is missing almost immediately - the Strobulb, which is what gives it the ability to flash a bright light in order to stun enemies and power up switches.
