It could be that they are different universes. It could be that maybe since Robby was there, though still a baby, maybe the stuffed bear stayed unanimated like the appliances and such do when adults are around. If there are some sort of rules some may interpret the rules more strict then others, or some may feel more strict about doing and not doing certain things. Or maybe it didn't really hurt. One could add the 2 together likely in an rp with little or no adjustments, I'd think.
