Our little fish was taken by Jojogirl 18 month ago. After a few weeks/months we asked if all is fine with our Buddy but we did not get an answer. We asked a second and third time, but always did not get an answer!
So today we marked it as missing.
It's always sad when trackables disappear from a cache but it is even worth, when an active geocacher looses them and is not able to say a word...
