To the Bottom!

Use an air bubble to lift sunken undead to the surface.

Something else came up. Some of our soldiers wandered off when we were marching from the Garden to the Outpost. I hear they were seen heading towards the lake. I suspect those unfortunate zombies are wandering the lake bottom now and feeding the eels. Please find them and bring them back to the surface.

That's everyone. I recounted. I hope they didn’t get too waterlogged hanging out on the bottom.
