[Pororo S3] #26 Poby is missing

Harry teaches Poby how to dance and sing, but Harry is not satisfied with Poby's performance. After being scolded by Harry, Poby quietly goes out of his house with a bag. Harry starts getting worried about Poby when he doesn't return after a while. He heads to Loopy's house with Pororo and Crong to see if Poby is there. He hears Petty say that Poby ran away, and thinks that it is all his fault. Poby was last seen by Petty at the ice lake. They head to the lake, but will Poby be there?
