From The New Archies:
After Reggie gives a karate demonstration, Archie dares him to come to a Halloween party at Frankenstein's Cave. However, the end result isn't what Archie had in mind.
Here's "I Was a Teenage Werewolf":
Edit, 2/7/18: As you can see, I had to change the video, adding the back-up episode, "The Prince of Riverdale", a loose adaptation of a certain Mark Twain story.
It looks as though DIC opted for a more anime style in drawing the beloved characters as junior high students. Small wonder, then, that The New Archies was a bomb, the 2nd time that NBC had failed with the franchise, and they had the cajones to bring the show back as a mid-season replacement a year and a half later.
