I find this quite a good Daffy Duck episode. Daffy is absolutely brilliant, but this is not really his episode. He is more of a side character. The people who are supposed to be the side characters and yet feel like the main characters, are Casper the Caveman and Fido the apatosaurus. You guessed it - this is set in the dino age. It is very incorrect to history, for example, humans have never been with dinosaurs. Luckily this does not spoil the episode. Anyway, unlike a few people on this site, I do not think Casper Caveman is the highlight of the episode. In fact, I think he is too harsh at points and it is only in the middle of the episode when he becomes slightly likable. Fido the dinosaur is likable throughout, very silly, cute and dog-like. Daffy is still in his early stage, with his constant "woo-hoo" and craziness, this is why he is so good. The animation is also pleasant as well. At this time the animators were still good, in later cartoons they just came up with any background that first came into their heads.
Casper the Caveman is very hungry and is ready for breakfast. Taking Fido the dino with him on his search, Casper soon finds Daffy. He tries to hunt him - but this little black duck is not going to make things easy for him!
Recommended to people who like the early Daffy Duck and dinosaurs, enjoy "Daffy Duck and the Dinosaur", a pleasant Looney Tunes classic to watch! :-)
