Found it! Hopefully going to put your little friend somewhere else in the upcoming week. I did give it a rub with a wet cloth with some cleaning materials, as the swan is getting a little weather-beaten. I'm not sure it helped much, but hey, it's the thought that counts. I also took some pictures, which I will include when putting the swan in a cache next week.
Thanks for letting me take care of your tag for a little while! :)
Best,
