stop motion 2

Welcome back to our stop motion! Here is our next stop motion video we made together it is 1:23 we have lego people. We have a ipad to take photos on the stop motion site. We had about 235 photos. The fun bit was... Doing the voices. I had to do two voices and Jackson had to do one voice. But he had more talking then I had to do. He needed a piece of paper to write on that's how much he had to talk. The lego was hard to do because they keep fulling over. That made it so hard but we did it together LIKE A BOSS!
