That was a very difficult three hours.
Dot was on the bedroom windowsill, where Grace has never before put a toy. It was a total fluke that I found him at all–she was helping me put some craft supplies away and I gave her a little butterfly bracelet that was in with my beads. She decided she didn’t want to wear it, and I went to put it away. I saw one of her necklaces laid out on the windowsill, and when I moved the curtain to pick it up I spotted Dot.
In the interim, I discovered (with a lot of googling) that Dot is a Beanie Baby named Hydrant. I am filing this information away in case anything ever happens to Dot, so we can get his “sister” for Grace. (I would never try to pull a switcheroo on her. She is too smart.)
