The Pirate Cove is a location in the Five Nights at Freddy's SMBX series.
This room is immediately availble for visit after the animatronics have advanced to the Dining Area. The Pirate Cove and the Dining Area are directly connected to each other via a wooden doorway.
The Pirate Cove is a small room that features a wooden floor and a stage made of wooden logs, which has curtains hanging from its ceiling and houses the Character Selection block for Foxy. There's also a small platform with a security camera mounted onto it, that is used by Mike Schmidt to monitor any animatronics moving around the Pirate Cove.
On top of the stage itself is one of the secret orbs, which can be reached by making clever use of the securtiy camera's platform as a stepping stone. Note, that due to his limited jumping height and necessary run-up, it is impossible for Foxy himself to reach this secret orb.
Only three locations in Freddy's Pizza allow the players to change their animatronics in mid-game without chosing SAVE & QUIT and returning to the main menu. The Pirate Cove is one them, with the other two being the Show Stage and the West Hall.
The Pirate Cove's Character Selection block is remniscent of the Foxy's initial starting position in the original Five Nights at Freddy's by Scott Cawthon.
This location is notable as it introduces the fourth playable animatronic in FNAF SMBX and the FNAF SMBX series in general. This animatronic is Foxy the Pirate Fox.
Note, that these tracks came with Super Mario Brothers X and the creator of FNAF SMBX takes no credit for the music in this game. All credit for the ingame music goes to Nintendo.
The Pirate Cove shares its overworld track with the Restrooms.
In Version 1.0 of FNAF SMBX, the Pirate Cove's layout is heavily based on the Show Stage. This is due to it being easier for the creator to reuse a similar layout than creating a completely new tileset and the game originally being made for only a small circle of people and not for a world wide release. Despite this, the creator stated, that this is going to change in the graphics update Version 1.1.
