Oink! Oink ! to communicate

Do you know how he uses this thing?

He uses it as a hand phone to communicate with people. He will talk while putting this thing near his ears. We cannot stop laughing when we have seen him using it.

Actually it is a key chain with the pig and piglet inside but it was broken as the animal cannot move anymore when you open the cover. We cannot imagine it as a hand phone but Ethan can. He said that this is his "Oink!Oink! Hand phone".
