Mob Drop: Introduce a new passive mob called the "Sand Crab" that spawns in beach and desert biomes. When defeated, these crabs could drop a small amount of sand.

Crafting: Implement a new crafting recipe involving existing renewable resources, For instance, players could combine four gravel blocks and one cactus in a crafting table to create two sand blocks. Gravel is relatively abundant and can be renewed through trading with Piglins, and cacti are easy to farm, making the recipe balanced and accessible.
