Under the ocean, you will see bubbles.
If the bubbles are moving down, you’ll get dragged down too!
They will pull you into a magma block (downward bubble currents are created by magma).
Soul sand creates a current which will push you up (water elevator build potential!).
If you’re careful, you can replenish your oxygen by briefly swimming into bubble currents.
As you can see, bubbles can be dangerous as well as useful.
