Riverdale [1]'s Halloween [2] episode is sure to be spooktacular! The CW unveiled photos for the upcoming episode, which premieres on Oct. 30, and it includes some of our favourite characters in costume. While Archie (KJ Apa) and Munroe (Eli Goree) don some very tight tights as superheroes [3], it's Cheryl (Madelaine Petsch) and Toni (Vanessa Morgan)'s couple costume that really takes the cake (or should we say bucket of candy?).

The power couple [4] are dressing up as the equally iconic comic-book duo Poison Ivy and Harley Quinn. Morgan even shared a full look at her sexy getup on Instagram, writing, "I'm Harley Quinn be my Joker." We can't wait to see what couple costume Jughead and Betty come up with! Look at the rest of the photos ahead, then see how you can dress up like the Riverdale crew for Halloween [5].
