First of all, I'm having some trouble figuring out how to rescue a couple of Mudokons.

They're in the second horizontal row, first vertical column-- the screen right under the starting screen, with the zapper, meat saws, and two Muds. There's no bird portal on this screen, and I can't get them to follow me off a ledge, so how am I supposed to be able to rescue them?
Also, on the left side of that screen above the lever there's a symbol. What does the symbol represent? I've seen it in several other places throughout the game so far.
Any help you can provide would be most appreciated.
