Yup only forever fix with this would be a Bin cage or a detolf/tank cage. He likes his freedom in his Ball so wants OUT now
These Hamsters are a lot smarter then some people think and if they find a way to get us to react they will grab it and run with it. If a different cage is not and option you may want to rearrange his toys ever so often so he thinks he has new ones. Make sure his wheel is of a good size as well as often if the wheel hurts to use they quite using the one toy which tends to keep them occupied and also exercised.
