So Mario lands in digital curcuit with all this electric kind of feeling to it and you see two gearmo's (I think thats how you spell it?) Anyway, the first one says, "Help us! These pesky goombas have shutdown our circuit board!" And the second one says, "Without our circuit boards, we'll lose our electricity!" So then mario continues on in search for the power switch in witch he encounters many goombas, then he is at the plug, then the battery, again with many goombas, octoombas, and all types of goombas. Also there are supposed to be alot of electric connected enemy things (the one mostly in space storm galaxy) and you have a few cyrstals filled with starbits.

So the main plot of this level that I think would work is that the goombas shut down the circuit board and they are guarding the switch which will, when activated, make a star appear and turn blue or red, whatever color it usually turns. Other gearmos you meet later in the level say thank you and you get your star.
