Mont Blanc Cricket

Montblanc Cricket (モンブラン・クリケット, Monburan Kuriketto) is an inhabitant of Jaya Island, living in a small home behind the facade of a castle.

History
Due to the (false) story about his ancestor Montblanc Norland, he is looked down upon and has become bitter to the point that he hates his ancestor. To that end, he aims to prove that the city of gold existed by diving into the ocean day in, day out, searching for any proof of it. He is later joined by Masira and Shōjō, two fans of the fairy tale who would become his surrogate sons. The Straw Hat Pirates soon come to him for more information on the "Island in the Sky," and how to reach it.

However, Bellamy the Hyena comes soon afterward and steals all of Cricket's hard earned artifacts that he found in the ocean. Luffy gets them back, however, and Cricket, Masira, and Shōjō modify the Going Merry so it can travel in the sky.

Near the end of the Skypiea arc, Cricket hears the ringing of the golden bell (courtesy of Luffy), proving that Skypiea and the gold city really do exist. Thanking the Straw Hats and relieved that they are all right in the sky, he, Masira, and Shōjō begin to think of a new dream to pursue.
