In the 2010-10-13 Content Update (51172), players were informed that there was “Prep for Halloween…” Sure enough just a few days later the 2010-10-18 Content Update (51312) arrived, stating, “Halloween has arrived in Pocket Legends. Talk to a Town Crier or see Halloween Hal in Forest Haven for details. Visit the Pocket Legends store for costume rentals and Halloween item packs.” Something to note is that they released a bug fix in another update, 2010-10-18 Content Update (51321): “Fixed issue with players being able to enter already completed Pumpkin Patch and Haunted Manor dungeon.”
