That is such an incredibly sweet story! And he looks amazing, considering he had been outside for a year! Good job with the rescue and rehab!
I've rescued a few toys that I've found outside, but nothing as epic as your story. One time I found a plastic otter on the ground when I was with my brother. I picked it up and put it on the dashboard of his car, and as far as I know it's still there.
The other best rescue I've done was when I found some very old, antique stuffed dogs at a thrift store. They were in pretty bad shape -- one of them is missing his nose, I think? Anyway, I could tell that they were antiques from the type of materials used to make them. I was afraid that they would end up being sent to a landfill soon, so I bought them and brought them home. So far I haven't been able to find anything out about them, like who made them or exactly how old they are. In fact, I probably need to post pictures of them on here and see if anyone knows anything about them...
