Harbet likes his comfy knitted hat, but the others keep jeering at him – OLD HAT! OLD HAT! No matter what headwear he buys – be it a towering fruit platter hat, an old-boot-on-the-head hat or a brightly lit traffic cone hat, Harbet cannot keep up with the latest fashions. As soon as he gets a brand new hat it is already an . . . OLD HAT! 

It seems that Harbet will never fit in. But when one day he decides to go his own way, Harbet discovers just how much more fun it is to stop following others and think for yourself.
