Cartoon Network Studios/Logo Variations

Third Logo Variants
Time Squad

Finn pokes Jake, as he becomes larger and larger, roaring and squeezing aside him.

Generator Rex (Season 1)

Rex turns his back into a jet engine, blasting off in the process while  smiling, but he crashes into the logo when it closes, which causes the logo to shake. Like with the Ben 10 variant, this variant uses the "Grungy" version of the logo.

Fourth logo variants
Regular Show (Seasons 1-4)

The right-most square features a clip from the episode "Prank Callers", whereas the sound clip of them laughing is from the episode "Death Punchies". There is an earlier version where it uses a clip from the episode "Free Cake", where Mordecai and Rigby chant "Free Cake!" twice.

Sym-Bionic Titan

In the right-most square, the Titan robot is seen with the camera panning up to its head, with Lance saying "Form Titan!".

Adventure Time (Seasons 2-5)

The right-most square features a clip from the episode "The Enchiridion!", with Finn saying "This party is so crazy!" This is one of the two variants where the fourth square doesn't turn white at the end.

The right-most square features a clip of Duncan performing his signature fire-breathing move.

Ben 10: Omniverse (Seasons 1-4) and Powerpuff Girls (2014 special)
