As with all aspects of life, what happens to you after death partly depends on your environment. Ubiquitous microbes might be chomping at the bit to rend you to bits, but dropping you in lava won't have the same overall effect as dipping you in chocolate and plopping you in a candy store. In the former scenario, you disintegrate; in the latter, you inspire cannibalism. In a not-so-similar vein, if your final resting place is waterlogged and saturated with iron, your body could acquire blue bling.
Per Atlas Obscura, these macabre decorations are vivianite crystals that form through the intermingling of water, iron, and phosphates contained in a corpse. As the process progresses, vivianite minerals transition from transparence to having a blue hue as oxygen joins the fray. This trippy transformation is further aided by bacteria. (Perhaps you're their equivalent of blue cheese.) Blue blotches subsequently occur on teeth, bone, skin, and proximate surfaces.
One of the more famous examples of vivianite-covered corpses was a centuries-old Swiss dude discovered in Switzerland's Lake Brienz, according to Live Science. He had become a mishmash of corporeal soap and blue crystals, and was horrifyingly headless. Investigators revealed that he likely drowned in a sediment-rich area, got masked by that earthy matter, and was later unearthed by earthquakes. That's not an ideal demise, but on the bright side, he was preserved in style.
