Below is a picture of what Mr. bunny looked like when I first got him and what he looks like now after a year of sucking on him and washing him at least once a week (because his ears and tail smell so bad from sucking them!).
The funny thing is mommy had a bunny, she named Cabbage, when she was a baby and slept with him every night (even took him on business trips) until she was 22! She said he was originally pink just like my bunny but by the time she threw him away (which she regrets now), he looked just like my bunny.
