Logo: We see the skull from the 5th Cartoon Network Productions logo, albeit redesigned and no longer with the Cartoon Network logo in its checkerboard teeth. Above it is the white word "CHECKERED" in an arc, and below is "PAST". Globs fly towards the skull as its bones fly away and the text trails off elsewhere. The globs turn the skull into the face of Dexter from Dexter's Laboratory as the background starts to pulse. Eddy from Ed, Edd n Eddy bites Dexter's head like a jawbreaker and stuffs it in his cheek. A fire burns over him, transforming him into Mandy from The Grim Adventures of Billy & Mandy. She in turn transforms into Courage from Courage the Cowardly Dog doing his trademark scream. It briefly changes back to the Checkered Past logo.

Variant: An extended version exists.

Technique: Monochrome 2D animation.

Music/Sounds: A calm, vibey beat.

Music/Sounds Variant: The extended version has the sounds of the bones rattling, crunching, fire flaming and a scream from Courage.

Availability: Debuted on a tweet by Adult Swim on July 17, 2023, and later used as an actual television bumper on August 30, 2023.
