I saw this film when I was 6 with my younger cousin, and we both really loved it. It basically follows the story of Happy Rabbit, who wants to become tougher and therefore adopts a new persona: Scrappy. 'Scrappy' and his friends have adventures while avoiding the taunts of Scrappy's older brothers, but the tables are turned when Scrappy's brothers get captured by a local farmer who sees them stealing his crops. Scrappy and his friend rescue them, and Scrappy realises that he doesn't need to pretend to be somebody else to be cool, and goes back to being Happy. It's not like Watership Down: here the animals all wear clothes and act like humans. The storyline isn't that great in my opinion, but the cute land that they live in with the lively intro music captured my 6 year old self. So if you want something to keep the younger ones entertained, this is worth looking at.
