"Sometimes, when people grow up, they forget how to have fun." These are just some of the words of wisdom spoken by Ted, the big raspberry coloured, fun-loving, troublemaking, imaginary best friend who arrives one morning to bring a boy and his father closer together. The father is too busy to spend time with his son, or even to appreciate the value of just having fun, but Ted has a plan to change all that. The plan involves painting portraits on the walls, impromptu haircuts and even creating an indoor swimming pool... but it works!
