The plot of this Christmas episode, "The Twelve Days of Krampus," features a beast-like creature from the folk traditions of the Alpine countries who is thought to punish naughty children during the Yule season. 

Mentzel plays a juvenile delinquent who tangles with this demonic goat-like creature, as seen in this preview of the episode. "Grimm," wrapping up its fall season, is filmed in Portland.

Mentzel has also appeared as a guest star on TNT's "Leverage," which also is filmed in Portland. He also has acted in local productions at the Cottage Theater, Actor's Cabaret of Eugene and Rose Children's Theater.

Mentzel, a South Eugene High School graduate, attends the Robert D. Clark Honors College at the UO and is pursuing studies in German, Theatre, Dance and Music. He is the son of Eric Mentzel, an associate professor of voice at the UO School of Music and Dance.

Mentzel said he's been auditioning and acting since he was 8 years old. Through his agent in Portland, he was called in to audition for "Grimm." After three callbacks, he got the news the part was his. 

"Oregon has a great, budding film and TV industry," he said. "I'm really excited to be a part of it."
