Mr Mountain has seen it all - from the arrival of the very first plants and worms, to dinosaurs, mammals, and, more recently... humans. Even when they climb all over him, Mr Mountain is very good at keeping calm and steady, and is determined to spend his long life resting his heavy arms and eyelids. Until one day, when he is disturbed from his slumber by a little voice asking him to 'Move, Mr Mountain!'.
It seems his neighbour Lily is desperate for him to move out of the way so she can see what's on the other side of him. But of course a mountain cannot move, and at this Mr Mountain finally loses his temper! The wind picks up, snow starts to fall and the ground begins to rumble and shake... but little Lily remains unfazed. Can they set aside their differences and find a way to get along?
