I take a simpler path. Put the skull in the canal and hope the gators don't make off with it. Crabs take care of the light work. Tusks on the bottom, pick 'em up and glue them back in place. Short soak in bleach,dry it out and go. 3 days in the water was all it took.
Resurrected:
Crabs gotta eat too.
And these clowns as well.
