Barney the Dinosaur is an anthrophomorbic purple and green Tyrannosaurus in stuffed-animal likeness, who comes to life through a child's imagination. He is best known for his friendly, kind, optimistic personality and positive attitude.
In the Barney franchise, his theme song is "Barney is a Dinosaur," whose tune is based on "Yankee Doodle". Barney often quotes things as being "Super dee-duper". Episodes frequently end with the song "I Love You", which is based on the tune to "This Old Man", which happens to be one of Barney's favorite songs.
Despite being a carnivorous type dinosaur, Barney likes many different foods such as fruits and vegetables, but his main favorite is a peanut butter and jelly sandwich with a glass of milk.
Other than his presence on the show, he is known to have a toxic hatedom (mostly from the GoAnimate Community).
