Notes

Two little men, one red and one green live on top of a signal pole at a busy intersection. The red man's job is to stop people from crossing the road, and the green man's job is to let them know when it is safe to cross. But one day, the little green man decides he's had enough of living on top of a pole and he runs away in search of adventure. Meanwhile, back at the intersection, the queue of people waiting to cross the road grows and grows!
