Beanbean Castle Town is the central location in the Beanbean Kingdom in Mario & Luigi: Superstar Saga. It immediately surrounds Beanbean Castle, and in the north part of the town, Queen Bean lives with her son, Prince Peasley, her ambassador, Lady Lima, and a plethora of advisers.
It contains a café owned by Professor E. Gadd, and four other miscellaneous shops (one for items, one for clothing/badges, one for information, and one for photography where the player can have their photo taken).
When the Mario Bros. arrive in the town, they discover that it has been destroyed by Cackletta. She stole the Beanstar and poisoned Queen Bean with the Belly Blech Worm. After Mario and Luigi obtain the Chuckola Reserve and return from Chucklehuck Woods, the town has been repaired. The town was destroyed again after the Beanstar was retrieved. As the game resets to the last point that Mario and Luigi saved at when it is completed, the town is not seen again.
