In this fresh teaser, the boys of Pentagon get ready to jump like green frogs, eventually running towards a giant frog statue together in the night. The title "Naughty Boy" is a modified version of the original title "Green Frog" (when literally translated). In Korean folktale, a green frog is a rebel, or a little rascal (a "naughty boy"), that does everything the complete opposite of what they are told to do.�

Watch the teaser to see Pentagon run around like fun, nocturnal amphibians! The full release of their new album 'Thumbs Up' will take place on September 10. Only a few hours away, so stay tuned!
