So, the curiosity bug bit me again. The mysterious part appears to be a Kre-O "Motion Brick" which appeared in various sets. In my research I found that there is a variation (hollow vs. solid) in the studs, as shown in the picture.

    This is very helpful, thank you! I have found out her Kre o blocks in the mix. My son kept asking me what it was and I had no idea! Thanks again!
