Lee Hwi Jae took the twins to a flour experience center for the development of their sense of touch. Contrary to expectations, the normally curious Suh Joon got scared of the pile of flour, while Suh Un, who normally has a lot of fears, turned the flour into his playground.

Lee Hwi Jae looked at Suh Un, who was all covered with flour, and told him, "Lee Suh Un. You became a bear. A polar bear." He also tried to get Suh Joon interested in the flour by jokingly putting flour on Suh Joon's face, but got an indifferent reaction.

Stay tuned for the flour action this Sunday!
