Strangely enough. my bunny is the exact opposite. He will anything and everything. One time, I gave him a piece of orange that was sour. He flicked his tongue in and out, trying to wipe it off with his tiny paws. I tried to give him water but he didn’t understand and didn’t drink any, so eventually I had to give him fresh vegetables. Funnily enough, once the sourness disappeared, he came back for more. I didn’t give it to him.
However, he was very confused by an ice cube. I showed it to him, and he licked it, bit it, and dug at it. He was so very confused! 
I think you’re bunny was just surprised by the strawberry, especially when it rolled. My bunny is deathly afraid of plastic bags just because it scared him one time. (I showed it to him, it got stuck on him, he took of running as fast as a bunny can which is pretty fast, and eventually it came off. Thank God, he would have died of fright if it didn’t. But the plastic bag was shredded to pieces by his claws)
