Stray Wally
From Super-wiki
During Salute to Supernatural New Jersey 2022, while signing photo-ops, Jensen noticed that in most photos he had one wayward hair in the photos, licking across his forehead. The Creation team members decided to name it and came up with Stray Wally. At some point Jensen added #straywally to a photo a fan presented him with and soon after it made it to Twitter. Fans posted many sightings of Wally under the #straywally tag, with sightings stretching back many years.
And yes of course Stray Wally now has its own Twitter account!
Note: Stray Wally is not to be confused with the hunter Wally.
