Nice.
It looks like the two sides of the mat can connect to each other (if you put the second sample on it's head), as the first sludge stream is 4 squares from the left edge away and the second one is 10 squares away from the edge of the left one.
Sadly this doesn't connect to "Map pack: Sewer System", which's sludge streams are only one square broad.
