Its not watership down. My memories are super fuzzy, since I must have seen it on tv sometime in the 90's.. But I remember:
Girlfriend/boyfriend being central tot he story
Ending on the note that the couple are having sex, but partly a gag on bunnies.. Having lots of sex
I also remember a big house full of this family of rabbits
And I might confusensome of it up with Biker Mice From Mars, but I believe mopeds were featured as well..
And the blood was from this battle with.. A dragon? Or a metaphorical dragon?
But it couldent have been a dream since I was discovered watching it, and my parents being apalled by both the blood and more than implied sex..
And they are dead now, so cant ask them for their memories
