A brief snippet from a "Disney Theme Song Takeover" in which "Amphibia" character Marcy Wu (voiced by Haley Tju) finds herself in the Amphibian village of Newtopia; she is so fascinated she doesn't see where she is going and tumbles down a long set of stairs.

Released officially on 1 October via https://www.youtube.com/watch?v=LYPGZ6zSNdw the "flight of stairs" moment has already seen several memes spawned:
- "where i fell down a flight of stairs" [sic] https://www.youtube.com/watch?v=RcONAJQEbPQ in which the end of every line is replaced with "where I fell down a flight of stairs"
- "Marcys falling down the stairs" https://www.youtube.com/watch?v=yuFB_KRRbZs in which the animation of Marcy is looped as if several Marcys are falling down the stairs at the same time
- "When Marcy Is Alone For More Than 2 Seconds" https://www.youtube.com/watch?v=xNG9ZA-KjPE which pairs a "Family Guy" clip of Stewie saying "This is more exiting than that time i saw Bobby McFerrin fall down all those stairs", followed by the "Amphibia" clip of Marcy falling with the "Bobby McFerrin" soundbite.
