Grok reaches down and feels something hard and regular shaped, but coated with a slimey sheen. When he pulls, what first emerges is some rusted bands of metal, then waterlogged wood, then something long and white... Several boney fingers clinging to a small chest! Boney arms follow, and then a skull and torso. Although truly dead, the corpse literally has a deathgrip on the chest. Finally, the arms break off at the elbow and Grok is able to move back ashore. The chest appears to be locked, and it is heavy and solid.
OOC: Amaury may never know if the 'pedes were gooey or not, since they fell in the river and washed downstream.
