I was just watching a Luigis Mansion 2 Demo Video and then i read somewhere that luigi is actually using an upgrade called the Poltergust 5000. Luigi is too of a luigi to get an upgrade of a machine without mario getting one too. Which could lead to a Sunshine 2. But the main reason of this topic is to discuss if you think if there is a Sunshine 2 how will fludd be upgraded and different as how the poltergust now has the flash thingy.
