Omae Umasou da na

Heart is a tyrannosaurus who is found and raised bv a herbivore mother. After learning his true nature as a meat eater, he runs away from home and finds a baby ankylosaurus egg that hatches and thinks Heart is his father. After accidentally naming the baby Umasou―thinking he looked tasty―their love for one another tests the bounds of nature vs. nurture.
