This venture follows the sold-out run in Korea, where pre-reservations filled within five minutes. The new MIGHTEEZ Wonder Room is taking place from May 8 to May 17, 2026, at LINE FRIENDS SQUARE locations in New York and Los Angeles as well as the brand's US online store. The pop-up event centers on characters created in collaboration with the [K-pop](https://www.trendhunter.com/trends/blackpink-popup-store) group [ATEEZ](https://www.trendhunter.com/trends/nacific), where each member is reimagined as a fairy possessing unique superpowers. The narrative framework of the pop-up involves a secret attic hideout where these fairy characters grow from babies into fully powered beings, a storyline reflected in merchandise such as plush keyrings showing them studying magic and Baby MIGHTEEZ versions featuring smaller ears and wings to indicate their early developmental stage.
