I finally found a toy that I could get my bun to play with... he's so picky!
I picked up one of the busy bunny willow balls from my local HRS store... at first he was totally uninterested... I thought he would like it because he loves to roll my hamster's ball around (maybe because of the scent?). I decided to put a couple banana chips and craisins in it to make it more appealing, and it really worked. He's rolling it everywhere and pulling apart some of the willow.
Here's a crappy little video I just took. A litte uneventful, but you can see him a bit in action. (The noise is my mom talking to the TV... Last Comic Standing, hah)
And a "what??" face:
