Cloud castle

The cloud castle is an extremely rare structure, maybe even more than the woodland mansion. It's found in the meadows biome, high in the sky, sitting on the new solid cloud blocks. Solid cloud blocks can only be mined with silk touch, as clouds are very delicate. But these clouds are solid. Inside the castle, there is new, club wielding mobs about the size of an iron golem called giants. Every once in a while, instead of hitting you, they might pick you up(technically force you to ride them, but with a different animation and the inability to dismount) and throw you. A new enchantment for boots, sky walker, can be found in some of the chests in the castle. This would allow you to right click to summon a cloud below you. But you can only have 3 clouds at a time, and they disappear after a while. Some rooms in castle include the hallway, the kitchen, the storage room, the secret room(sky walker found here), and the throne room. The giant king can be found in the throne room, but I'm all out of ideas. Comments help though. That's it for now.
