Masked Mustache! is the twenty-first episode of The Melancholy of Haruhi-chan Suzumiya.
Haruhi, Mikuru, Yuki and Tsuruya attend a mall exhibition whilst Kyon and Koizumi attempt a puzzle. Tsuruya fights against one of the show's monsters, who is really Mori, but is inevitably defeated. In the wake of the clash, Kyon and Koizumi's puzzle is ruined, leaving them frozen in place.
- Beard Mask is an obvious parody of Tuxedo Mask from the Sailor Moon franchise.
