Type in any Christmas song and see what the little puppets do. Also, type in any non-Christmas song (I typed in Happy Birthday) and you'll get a kick out of the response. One of the funniest I typed in was Jingle Bell Rock... they forget the words half way through. http://www.sundog.net/carolofthechins/flash/card.swf
Oh I loved that!! I see what you mean about Jingle Bell Rock - hilarious. I asked them to sing 'Little Donkey' and they just looked confused and then said they didn't know it. I'm off to have another play
