Resonating Crystals

There should be more geodes, like Echo geodes and maybe Enhydro geodes that can be put on display. also, crystals should grow faster if there is water or lava dripping on them, depending on the type. There should be a adjustable spyglass that uses Echo shard, and also a Enhydro spyglass that can see really well underwater, and to balance that out other spyglasses shouldn't work very well on water. There could also be a version of the Echo spyglass that uses glowstone to outline anything that makes a lot of noise. There should be calabrated skulk shriekers that have a echo shard in them and summon the warden with the slightest vibration and make really loud noises when being destroyed(these could be crafted for devious purposes.. Enhydro crystals would be found in the End, and yes, they are real crystals.
