[Pororo S2] #49 Whats this smell?

Today, everyone is gathering at Pororos house. Poby ate too much before, so he keeps farting on his way to Pororos. While theyre playing with blocks, Poby keeps running outside to fart, and his friends wonder whats going on. In the end, Poby cannot hold it any longer, and he farts in front of his friends. Everyone runs outside because of the bad smell, and Poby says sorry to his friends.
