Sinkable Mud (Like Powered snow, turns Skeletons into Boggeds)

With the addition of the Bogged, like most undead variants, there should be a way to convert its normal counterpart into it such as Strays from powered snow. Since the Bogged is called “The Bogged”, I think it would make more sense if it was formed from sinking into the mud rather than being submerged as the form of “sinkable mud” Sinkable Mud would generate in patches within swamps and mangroves, encouraging players to wear leather boots more often. It can also be bucketed like powered snow. Any players and mobs (maybe except for frogs?) that get in will simply suffocate and perhaps, it can be harder and more tough to escape than powered snow.
