I think the unicorn and tag became separated and the tag is what is sitting in Lake of the Woods (in IL), because today I found the Unicorn inside of https://coord.info/GC7Q9TY Thestral (in WI). I retrieved the unicorn, which was inside a Ziploc bag with the trackable info sheet. Contacted the owner to get the tracking code and wrote it on the info sheet. Owner requested I retrieve it from Lake of the Woods and I'll pass everything along at the next available cache of a suitable size.
