planet of the sky

I think there should be a new dimension the name can be voted on where there is kind of like a foreign planet where it is mostly sky islands and under them is a endless sea it would have poisonous clouds and the air would have a blue tinge. it would have new blocks like cloud blocks at the bottom of the sky islands they would we intangible. also it would add mobs like poisonous fog and warped pigs. also maybe you should add a new moon in the sky for it. also it would add new types of fruit and maybe a poisonous fruit.
