Quicksand

There would be quicksand spawning in deserts and beaches having a similar effect to powdered snow where it gives the desiccated effect. The desiccated effect gives you sand in the corners of your screen instead of snow and it also gives you nausea and slower over time with damage if you have it for too long. The effect can be cured with water bottles making bringing water on your adventure needed. Much like how powdered snow makes skeletons and zombies their frozen counterparts, the quicksand would make the skeleton the parched, and the zombie the husk. You wont have to add this but i thought it could be a fun idea, the palm tree, the palm tree can spawn at beaches and deserts could have a new area, the oasis. The oasis could have a pond or lake of water that has quick sand and grass and moss around it the palm trees could also spawn there. One more thing, maybe there could be a new type of village at the beaches where its made of palm tree planks called the coastal village. The coastal village could have a dock or two with fishing villagers and boats by the dock and some of the houses could go into the ocean like a over-the-water bungalow.
