This guide will tell you the method to design Water Lily in the Minecraft game.
The first thing you need to do is to place a spruce trap door in the water and add an item frame at its top.
And then add a sunflower on the item fame. Follow the same to add 3 more trap doors and then item frame and sunflower.
The next thing you will need to do is to add different corals on the sunflowers. Add a fire coral fan on one, tube coral fan on the next and bubble coral fan on the final one. This will complete your design of water Lily.
