Lucy Lawless is returning to "Parks & Recreation" (Thursdays at 9:30 p.m. ET on NBC) for the show's Halloween episode.
In the clip below, Diane (Lawless) takes her kids trick-or-treating with Ron Swanson (Nick Offerman) -- decked out in his go-to pirate costume -- and Andy (Chris Pratt), who is dressed as a cop. Lawless' character is dressed as one glam princess, a far cry from the warrior princess she's known for.
Diane's kids are decked out in princess costumes too. "All princess, all the time," Diane tells Andy. "It's a nightmare."
Here's how NBC describes the episode:
HALLOWEEN SPIRIT IS GONE WHEN LESLIE GETS SOME BAD NEWS—LUCY LAWLESS GUEST STARS—A new job offer for Ben (Adam Scott) causes Leslie to contemplates their future. Meanwhile, Ron (Nick Offerman) and Andy (Chris Pratt) take Diane’s (guest star Lucy Lawless) girls out trick-or-treating, and Tom (Aziz Ansari) searches for a new business idea. Rashida Jones, Aubrey Plaza, Rob Lowe and Retta also star.
"Parks & Rec's" "Halloween Surprise" airs Thursday, Oct. 25 at 9:30 p.m. ET on NBC.
