The f(x) members mimicked each other, leaving a lot of laughs for viewers.

On the June 25 episode of MBC Music's 'Amazing f(x)', Amber came up with the idea of imitating the various habits of the members. Krystal went first as she mimicked Amber. She imitated Amber's random dance as well as the way she tends to practice a body wave looking at the wall. Apparently, Amber also has a habit of becoming Sulli's guardian and she always says 'Our Sulli, our Sulli'.

Luna also imitated Krystal and the way she flipped her hair or rolled her feet duringaegyo, as well as her habit of keeping all her weight on one leg when she sang on stage.
