I'm just guessing, but I have a feeling that those are probably made so that they can take the electronics out easily and just throw away the plush part and put the electronics in a new plush each time someone rents one. As little as it probably costs to make one of those, I imagine they wouldn't go to the trouble of trying to sanitize them or something, just throw away the plush part each time. When they can sell a non-electronic Mickey plush for 12 dollars or whatever it was the last time I was there, you know it probably only costs a few dollars to make the plush part, so they'd still be making money on renting and throwing the plush part away. Of course they're also counting on many people ending up taking them home too, and not returning them.
