How old is E.B.?. Because on the website it says he is a teenager but in the film it says he did not meet 费雷德 until 20 years after he was shown as a young rabbit at the beginning of the film. What age can he be?.

Well, let's say that when he was a child, he was 3 years old. That means that now he is 23 years old.
But this doesn't add up with what the website says, so I think that why they say he is a teenager is because he looks a lot cuter as a teenager, they needed to 显示 him as young to get the people to start loving him and the reason they 说 20 years later is because they needed a big number ;)

Yeah, I saw that too. But Maybe he's 20 或者 so. Let's say he was just a baby at the begining, which I think he was. Than he'd be arround 20. I guess some people consider that a teenager.
