B1A4's self-advertising for their upcoming concert caught much attention.

Today, B1A4's leader Jinyoung and member Sandeul revealed pictures of B1A4 members in animal suits. Jinyoung wrote, "B1A4 dolls! Did you meet them this morning?", and Sandeul wrote, "I don't like the kid that pulled on the duck's tail earlier."

In the picture, B1A4's members are transformed into bears, squirrels, ducks, kangaroos, and other animals. B1A4 members had advertised for their concert in front of a school wearing those animal suits.

Internet users who found out about this commented, "I didn't meet you, please come one more time", "They're so dedicated," and "They came to our school today."
