This is a very easy song, suitable for children or beginners. You can use it to revise the names of animals. Use it definitely at the end of the lesson, preferably on Friday as the kids might not be able to pay attention any longer after listening to the song. Friendly warning: please, be careful, watch the song before you play it, you might find it a bit silly, but definitely funny. YouTube video is here: http://www.youtube.com/watch?v=jofNR_WkoCE
