Norn Home

The biggest problem about the norn habitat it that the fish go extinct. To solve that download the fish food agent. (available at http://members.xoom.com/tsi333/c3cobs.html) To solve the over all collapse attach the pulse switch (make sure its on) to the cloud control thing at the top right of the norn terrianuim.

The biggest problem here is the extinction of the gnarlers. To fix this just have the volcano make more rocks. One way it to attach the output of a pulse switch (make sure its on) to the input of the volcano control. I must warn you though you'll have a ton of them in no time at all.
