On October 2, a reaction video was posted on the girls' YouTube Channel, Twin TV.  And with Halloween approaching soon, the members got comfy on their couch to watch 'World War Z'.

The twins left a cute message, saying:

"Hi guys! This is Twin TV. For our 'Overcoming a Horror Movie Project', we originally started to watch the movie 'Final Destination'. However, from the beginning of the movie, we almost felt like fainting. We decided to replace it with the zombie movie, 'World War Z' and filmed our reactions. Thank you for your understanding. This is also a big challenge for us! Haha Enjoy our video! and Hope you have a fun Chuseok ?"

Were sisters be brave enough to tolerate the zombie-infested apocalyptic movie? Watch as the duo cringe, and scream in unison... even cheating (covering their eyes) at the scary moments.
