Lily Pads are flat, plant-based blocks that naturally generate on top of water in swamp biomes and sometimes in forest biomes. Players can collect them by breaking with any tool or by hand, and they can be placed on the surface of any water block. They serve as platforms that entities can stand on without sinking into the water, and they can also be used to create paths across water bodies without the need to swim.
