I'm sorry that one of their wheels was not moving as easily, but it is a good thing that you noticed it and their hasn't been any disputes concerning it. Rhubarb and Crumble really are sweethearts. I look forward to seeing how they enjoy their next wheel and their flying saucer. It will be wonderful to see them running and enjoying themselves on their new toys. I look forward to seeing their pics on the flying saucer, too.
