2nd Logo (September 30, 2018-January 13, 2019)

3rd Logo (February 16, 2020-October 18, 2022)
Logo: On a black background, we see an box with Cinco De Mayo-esque patterns all around it. In the middle of it are two skulls connected to each other with patterns for the left one (representing Julie Thacker Scully's customized skull) and  patterns for the right one (representing Mike Scully's customized skull). Above it is "SCULLYS" in a rocky bubble font. As the sparkles around the text shine, the eyes of the skulls light up in yellow and click their mouths.

Technique: 2D flash animation by Marissa Fonte.

Music/Sounds: A shining-esque sound, alongside clicks from the skulls.

Availability: Seen on Duncanville.
