Why it worked
The video leverages the visual appeal of popular Disney characters and the satisfying ASMR-like action of flipping through a large collection of books. The clear numbering of each book (e.g., 35/35) creates a sense of completion and order, appealing to viewers who enjoy organized collections and satisfying visual sequences.
Summary
The video showcases a large collection of Disney-themed "Coloriages Mystères" (mystery coloring books). The creator flips through various volumes, displaying covers and interior pages featuring characters from different Disney franchises like Barbie, Boule & Bill, Scooby-Doo, Moana, and various princesses. The video is a visual cataloging of the collection.
