After Mona accepted one of Crescents Tea invites, they hit it off good. Mona Had alot of fun that he personally asked Crescent to move to TurtleReef, which he did. Him all 9 Shins and James moved to TurtleReef. They moved into a cave in the mountains above the outskirts near a temple where Crescent studies Archaeology. Since Crescents not involved with the Palace, he doesn't have to wear their colors, so he had one customized himself, also like Mercury he has his open to show off his pamp.
The guards are aware of Crescents antics, so he's not allowed near the palace unless accompanied by the guards, or if he accepts one of Mona invites. The captain of the guard keeps a close eye on Crescent since he's known to mail a stinky kitty diaper or plushie back to the palace, specifically to annoy him. He's also not allowed near the palace since he and Mercury don't get along, but under Monas orders, they can't fight each other so they're known to fight in arenas held on the island.
When Mona accepts one of Crescents invites, Kimo goes with him since Mercury won't go near his cave. Like Mercury, there's also tourney themed around him that he partakes in. Most of the Mona will have Mercury and Kimo handle a job or a few errands so he and Crescent can have a pary. Of course Shin and James aren't too far behind to join in the fun. Unless Mona orders, the guards have to stay by Crescent since the guards and Juan don't enjoy his antics, but he doesn't mind. He loves living in the Kingdom, lots of fun diapers and plushes about.
