There was some confusion with this little guy.
When I found the him the container was busted and water had been collecting in and out for a few months. He had rust all over and was not connected to anything.
He was originally believed to be Boardwalk which was listed in Dead End (GCKB63). After he had a nice hot bubble bath and a good nights rest, I decided to see where he hails from. Found that the code is actually for another trackable, "Monhina's traveling cup cake" (TB6R33Y).
Due to the condition of the cache, I was not able to salvage the cupcake, but needless to say... this is not Boardwalk.
Boardwalk is not in Dead End and it appears that he is on some other adventure.
