There was some special anniversary events on when Tibia got 10 , 15 and 20 years , but this year is not a special or round number so I think it will be a normal anniversary event where during this time you can visit Nostalgia Island again where you can hunt monsters with the old monster sprites, dig for treasures or knock down cans. The pinata dragons will also be spawning everywhere.
