Special dungeons get delivered to your doorstop by the green postman, more frequently if you clear more dungeons. You have to cast the spell for it to appear in your list, and sharing the spell with others (via Twitter) will reward you a free daily gift (sometimes rice balls!).
Also, searching for a specific dungeon and casting multiple will allow you to get multiple at the same time. Higher level dungeons will have slightly better drop rates from higher level enemies. You can hold up to 99 dungeons of each type (although possibly more but it displays max of 99).
