Dang John, your urchin is a LOT fast than mine

Mine will bring things out from behind the rocks for me if I drop something. It will NOT, however, bring back the things that it drops behind the rocks. Right now mine is quite pleased, he has a featherduster, four shells, some algae, a zoa, and a frag of birdsnest. He's gotta have a stash back behind the rocks, because his wardrobe changes daily.
