Bundle and Aquifer changes

Aquifers

Currently, Aquifers look quite strange underground. You can find Stone, Diorite, Andesite and other blocks which you usually don't expect to generate underwater. I think Aquifers should have Cold Aquifers and Warm Aquifers. Cold Aquifers have kelp and a lot of sand and gravel like Cold Oceans. Warm Aquifers can generate with coral reef, tropical fish, kelp and a much warmer looking water like the Warm Oceans. These additions would make Aquifers feel much more lively and beautiful.

Bundles

In Minecraft, a type of item that clogs up your inventory heavily is unstackable Items. Item's like potions, weapons and more take up a lot of space. I think you should be able to stack unstackables in Bundles. I think each unstackable in a bundle should take up four slots, meaning you can only put 16 unstackables in your bundle.
