Aha, just what I (probably? maybe?) needed: a tin with six Peanuts hang tags from Oh Scent. Snoopy is fruity, Linus is powdery, Charlie Brown is green. $40 (about $30 more than I would have guessed) at Nordstrom, where you'll also find Peanuts Car Clips Air Fresheners ($48).
What? No pigpen!
Ha! He would have been perfect for scenting any area!
Seriously! They could have scented him with vetiver.
Or a really dank patchouli, maybe?
