[REQUEST] - Boiling Earth

I noticed Wc3 seems to have a strange lack of spell effects involving bubbles.

Im asking for someone to create an Spell friendly Sfx that causes bubbles to erupt from the ground, in a random field pattern

Think Lava or Volcanic Mud.

How solid do the bubbles need to look?

Well they should look like they made of Magic/liquid of some sorts.

But something more noticeable than doodad bubbles should be good.
