Other than the Plush and other Merchandise Items, the cutout in front of the Hyperion Theatre is basically it.
I've heard (I think it was Jim Hill, though) that they were testing out a character who could have gone into the parks, as seen above. It would have been somewhat similar to PUSH the talking trashcan.
However, there was apparently no way they could have sent him into the Parks without running the risk of him running over people's feet. He was apparently much heavier than PUSH as well as being much smaller and less readily visible, so there was a real risk that he would've crushed someone's foot and potentially sent them to hospital.
