What is the Hippo Pathway AI Trend: What If You Were a 500-Foot Pop Star??
"What if a pop star was 100 times taller?" That question, a low-poly 3D singer in a gold sequin dress and a wordless "oh-eh-oh" hook turned into the Hippo Pathway trend, one of the most shared what-if videos of the autumn. Upload one photo and this template makes you the giant: a 500-foot pop star in gold sequins dancing down a city avenue while the taxis stop at your boots.
The trend started on 7 October 2026, when the science what-if account @man_ia_c posted the first clip. The caption explains the name: switching off the Hippo pathway, the signal that tells organs when to stop growing, made mouse livers four times bigger, so the video asks what a singer would look like at 541 feet. It passed 5.9 million views and 43,000 shares. A sequel, "What if a pop star grew 10 billion times taller?", added 2.6 million on 26 October, and viewers started calling the music the Hippo Pathway song. Other creators answered with their own versions: @weltghost's "What if all 8 billion people came to her concert?" reached 1.7 million views on 6 November, a cover by @.yo.soy.aaron passed 1.2 million, and #hippopathway now holds more than 5 million views.
The template runs in two steps: an image model draws you as the giant pop star in the low-poly 3D look of the original, then a video model plays 8 seconds of dancing down the avenue with a wink at the rooftop camera and an original wordless pop hook. The trend videos on this page are credited to their creators; the poster image is AI-generated.
What happens in the video
0-3 s: you dance down a city avenue as a 500-foot pop star in gold sequins while cars stop around your boots. 3-6 s: a low angle from the street as you strike a pose. 6-8 s: you lean down to the rooftop camera, wink and dance on.
Why is it called Hippo Pathway?
The Hippo pathway is a real growth signal in the body. The first video's caption says switching it off made mouse livers four times bigger, and asks what would happen to a pop star. Viewers then named the music and the whole trend after it.
Which photo to use
One adult with the face clear and toward the camera, or your own cat or dog. Use your own photo or one of someone who said yes, never a celebrity, a stranger or a child.
