Mario and Luigi were in the mansion where Luigi used to relax in.
"Hey, Mario. I'm looking for just the right poltergust." Luigi told Mario. "That way, with my new poltergust machine, will make ghosts frightened."
"Well, Luigi, I think you should try asking Professor E. Gadd if the poltergust works first." Mario told him.
"You know what, Mario? Maybe you're right. I should tell him that." Luigi said.
