A Message About Clams (Unrelated to Stacking)

Off the southern coast of Venture Bay in Northrend, my Find Treasure skill detected some simple "Clam"s under the sea. Curious enough to drop down and have a look inside (perhaps for pearls) I was surprised to discover that the clams contain basically the contents of an old-world treasure chest of, say, Dun Morogh - a Shiny Red Apple, some Darnassian Bleu, a Frayed Cloak. More interesting than that, however, was the fact that some five seconds after emptying the clam, it respawns - Tough Jerky, Bent Large Shield, Frayed Shoes, et cetera. So I popped a Nagrand Cherry and stayed around to empty it a few times. The monetary amount is never more than around 11 copper, so it definitely doesn't pay to sit and exploit it... but it was a strange find, nevertheless.
