The sequel to Happy Feet is about Mumble's son, who does not want to dance. The trailer does not make it seem all that interesting, as there is not much to it, but it actually makes me totally uninterested because it some rap hip hop thing and I do not like that kind of music. However, the graphics look nice and it is going to be in 3D, so that sounds kind of cool. Plus, its still penguins and set in Antarctica.
The end of the trailer is also kind of disturbing with the little penguin looking like he is being hung and then the seal kind of eating him to pull him back up.
