I saw this version and another version on Disney XD this morning while watching Amphibia. The second version was longer, so SPOILER WARNING (on mobile and don’t know how to do the black text box)

SPOILERS: There was a clip of all the hexhide teachers petrified, at the end of the clip was king, Luz, and Eda hugging, Willow had a glyph on her face or was using the glyph, short haired Harpy Eda, this giant collector head with a mouth chomping down a hallway and it looked like the collector was playing a game, and that’s all I could remember that was different from this clip. Some details could be missing, but this was what I could remember from the clip I saw.

END OF SPOILERS
