Thank you all so much for the feedback, the links, and most of all, the help in finding Mira a new toy. We were able to track one down through a link some friends posted on Facebook. A seller had one up on Ebay awhile back that didn't sell. I emailed them, they put the listing back up and we were able to get it! At least now we know we have one on back up - it's on the way.
In addition, a friend offered to look at the old toys to see if any of them could be repaired. Her husband dabbles in electronics and he said he could take a look at them. Even if one of them can be salvaged, it would be awesome!
Again, thank you all so very much for all of your support and keep a lookout for other ones - have a great new year!!!
