Oliver is a young boy who loves playing with his friends who happen to be puppets, stuffed animals and toys.  He realizes he is a little different than the other kids, and he is comfortable with that reality.  He delights in imaginative play and is always involved in an adventure of some sort.  With time, he wonders if a human friend might be someone who would be fun to share adventures with as well.  A run away tennis ball sets the stage for an opportunity to meet Olivia who is a little bit different herself and a perfect friend for Oliver.
