Kureyon Shin-chan: Densetsu o yobu odore! Amîgo!

It all begins when Shin chan and his friends realize that teachers and peers behave more rare than usual. When they begin to investigate, conclude that the city of Kasukabe is filling clones. Appears to be identical to another and no one can avoid it, the real one disappears completely. All they know of these clones is that they like to dance samba! This information helps them figure out what people around are not real, because once the music starts... they can not stop moving their bodies!
