Molly Quinn wears her green proud as she attends the premiere of The Muppets held at the El Capitan Theatre on Saturday (November 12) in Hollywood.

The 18-year-old Castle cutie took to Twitter to express her sadness that her favorite Muppet was a no show. “My true muppet love is Rizzo the Rat. He always obeyed his mother and never carried the plague, not even once. :)” she posted.

Molly also just signed on to star in Black Forest: Hansel and Gretel and the 420 Witch, Variety reports.

She’ll play Gretel, opposite Michael Welch and Lara Flynn Boyle. The pic follows a witch living in Pasadena who lures teens into her house with a special blend of marijuana so she can eat them in order to maintain her youth.
