After visiting cats on the previous episode, Lee Hwi Jae took the twins to see fish, which the twins also have an interest in. They caught eyes in their adorable matching aprons, drawing a crowd who couldn't help but smile as they watched the twins look around with curiosity.

Stay tuned for their trip this Sunday at 4:50 PM KST!
