Dweeb is one of the supporting protagonists in We're Back! A Dinosaur's Story. He is a hilarious and dim witted Green Parasaurolophus walkeri and he is voiced by Charles Fleischer, who voiced Roger Rabbit and also voiced Babar the African Elephant.
Don't think a story like this exists. Add dinosaur / prehistoric characters to the relevent species. No modern animals, there are other stories for general species.
