There is more than one artist with this name: 1) Barney is a purple dinosaur from our imagination, and when he's tall he's what we call a dinosaur sensation. Barney's friends are big and small they come from lots of places. After school we need to play and sing with happy faces. Barney show's us lots of things like how to play pretend, ABCs, and 123s, and how to be a friend.
