"Big Island" Mike Mapu runs Big Island Mike's Immersion Excursion, a detailed vacation operation on the big island of Hawaii.
In 2006, Mike has Frank and Joe doing an immersion excursion. They are there to investigate him and his daughter Pua in order to make sure Pua is okay to be used in an advertisement for Aikens Biotech. However, the real reason they are there is to find out why the Mapus are spreading rumors that the Hilihili research center is destroying the local pineapple crop, as Richard Aikens, the CEO of Aikens Biotech, also owns the Hilihili.
It turns out Mike would inherit the Hilihili if it were to go out of business, which may have something to do with him being a former pineapple grower. He brought fritillated flag beetles to Hawaii so that they would destroy the pineapples, and then blamed it on the Hilihili's research. He needed money to pay off Johnny Kuto, a man who sold stolen items to a pawn shop that Mike was harboring for him. When Frank finds this out, Mike confesses his plan to authorities.
