Det. Nick and Hank will have to stop another terror from ruining the Christmas spirit in the next all-new episode of NBC's "Grimm" on Friday.

Last week, a bunch of gremlin-like little creatures set out to destroy the holiday spirit in Portland. The threesome of little Wesen known as Kallikantzaroi haunted the residents of Portland while trying to ruin all festivities and seasonal decorations. The creatures even eventually make their way into Rosalee's home while she and her best friend Juliette are the only people there.

Now, Nick and Hank will face off with a notorious Latino beast called the el chupacabra.

The trailer video for the upcoming episode, which is aptly titled "Chupacabra," shows that the blood-sucking beast will go on a ballistic killing spree after being brought to and released in Portland. As a result, Nick and Hank will have to figure out a way to stop it.

Meanwhile, a preview clip reveals that Wu will become very suspicious about the latest string of murders in Portland. In addition, Wu has been trying to have a serious discussion with Nick about Trubel.

According to Carter Matt, the official synopsis reads as follows:

"An unsuspecting traveler brings a blood-sucking legend with him to Portland, and Nick (David Giuntoli) and Hank (Russell Hornsby) find themselves investigating the gruesome trail of "El Chupacabra." Meanwhile, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) prepare to leave for their long-overdue honeymoon as they are met with more threats regarding their marriage. Elsewhere, Viktor (guest star Alexis Denisof) and Adalind (Claire Coffee) decide to take a trip of their own, while Wu (Reggie Lee) decides to confront Nick about what he has been seeing."

Season 4, Episode 8 of "Grimm," "Chupacabra," premieres on NBC on Friday, Dec. 12, at 9 p.m. ET.
