Yes, we use the same word "piñata" in English. In the U.S.A. there are a lot of Hispanics, so using this word really makes sense because they invented it.

Thanks all of you for your answer..

We use the same word in English, piñata.

There's no direct way of translating piñata into English. The best way would probably be to describe it to someone; most people know what a piñata is anyway haha.
