For the past four seasons, "Pretty Little Liars" (PLL) looked forward to the extraordinarily creepy Halloween episodes every year, wherein more questions about A and the girls were left unanswered.

This year, the creators of PLL decided to break tradition and offer a Fans Appreciation episode instead of the usual spooky one that they have been doing since the show started.

The PLL Halloween Special Season 5 will feature Lucy Hale, Ashley Benson, Troian Bellisario, Shat Mitchell, as well as the other cast members in a one-hour episode.

Fans can ask the Liars questions by posting them on the official Pretty Little Liars Facebook page or by submitting them on Twitter using the special #PLLHalloween hashtag.

Fans can ask the cast anything, except about the real identity of A, of course.

Janel Parrish, the actress who plays the role of Mona Vanderwaal, talked about the upcoming Halloween Episode after her character died during the summer finale.

"The Halloween episode is a fan love letter from us where we show the last five years in clips and interviews with us." Parrish said.

Meanwhile, in lieu of the usual spooky Halloween episode, creator Marlene King said that they are preparing a special Christmas episode, which Parrish further commented on by saying, "I will be in the Christmas episode, which is like the new Halloween episode special, but it's still an episode with lots of questions and answers..."

The Christmas Special, written and directed by King herself, will be a first for the series. It will be titled "How The 'A' Stole Christmas," and will feature a lot of scary stuff that the Liars will have to go through after Mona's death. Seems like 'A' does not want the girls to have happy holidays this year, right? It will air sometime in December.

On the other hand, the PLL Halloween Special will be shown on Oct. 21. on ABC.
