History[]
Both him and his assistant, Rob met the gang at the museums main hall. After introducing themselves he got into conversation with Fred on why the museum was completely devoid of people, to which he replies saying that nobody has been coming to the museum because people have been claiming that monsters have been sighted around the exhibits hallways. He then said that he'll have to close down the museum, but was soon relieved that they'll help solve the monster problem.
He was later brought over by Daphne to see that they caught the monster and was surprised when he found out that his own assistant was behind it all. Rob was sick and tired about the kids with dirty hands touching his displays and went around as various monsters to scare them away.
After the case was solved, Mr. Mason thanked the gang for doing a terrific job.
