Possibly a tie-in to the new release of It's The Great Pumpkin, Charlie Brown! There was a series of different Halloween figures before, but these are brand-new.
I went into a CVS store on an unrelated matter and found them there: Lucy and Peppermint Patty. Apparently Charlie Brown and Snoopy as the more popular characters had been scooped up already. I am going to check again later in case they get re-stocked, or at any other CVS I get close to. Each cost $6.99.
Lucy comes with a pointed red hat with stars, a white sheet costume, and a tub of bobbing apples. She is as she appears after the trick-or-treating at the Halloween party.
Peppermint Patty is an interesting case. The show was actually made before Peppermint Patty was established as a character. But somebody was in the hat and green mask and sheet costume that comes with the figure; it could have been Shermy or Patty or Violet or some other secondary character. But Peppermint Patty is more popular now, more well known, so it seems she was slipped into the anonymous role.
