Once the camera pans down to Danger Mouse and Penfold's starting position, you shall immediately have to switch to Penfold, jump over a gap with an electrical force field under it to land on a platform and walk onto a red button to turn it green and deactivate the electrical force field (but if you walk off it, it will reactivate it again!); once you've done so, you will have to switch back to Danger Mouse, drop down to another platform, jump back to the left onto a third platform and collect the first "DM" badge. You shall then have to switch back to Penfold, climb down a ladder to the second platform (reactivating the electrical force field in the process), activate Penfold's shield, switch back to Danger Mouse, jump back over to the second platform, pick up Penfold and throw him so that he falls through another gap with another electrical force field over it to land on the ground - and, once you have done so, you will have to switch back to Penfold, deactivate his shield and walk onto a second red button to turn it green and deactivate the second force field (but for the second time, if you walk off it again, it will reactivate it again). You'll now have to switch back to Danger Mouse, drop down through the second gap (and the now-deactivated second force field), switch back to Penfold and jump up onto a third red button to turn it green and deactivate a third electrical force field (reactivating the second one in the process, and if you walk off the button you have just jumped onto again, it will for a third time reactivate the third force field again); once you have done this, you shall have to switch back to Danger Mouse, jump onto a vertically-moving platform (passing through the now-deactivated third force field in the process!) and a third platform in turn, throw a switch to activate another vertically-moving platform, fall down onto a fourth platform, and jump up to that second vertically-moving platform and a fifth one in turn. You'll then have to switch back to Penfold, follow Danger Mouse's path up to the fifth platform (reactivating the third electrical force field in the process, and you will only have to jump onto the second vertically-moving platform to get to it), activate Penfold's shield, switch back to Danger Mouse, pick up Penfold, and throw him across a third gap to pass through a fourth electrical force field and smash through a stack of three crates on a sixth platform - and once you have done so, you will have to switch back to Penfold, deactivate his shield, throw another switch to deactivate that fourth electrical force field, walk back to the left, drop down to a seventh platform, climb down another ladder to the ground, crawl to the left and collect the second "DM" badge. You will then have to climb up a third ladder, crawl to the right out of a hole in the wall, jump onto a third vertically-moving platform and back onto the fifth platform in turn, switch back to Danger Mouse, pick up Penfold and throw him back across the third gap to land on the sixth platform; once you have done so you will have to drop down to the third vertically-moving platform, jump up to that sixth platform, fall down to a fourth vertically-moving platform and the ground in turn, and collect the third "DM" badge. You'll then have to: switch back to Penfold, follow Danger Mouse's path down to the ground, switch back to Danger Mouse, pick up Penfold, and throw him up to an eighth platform - and once you have done this you shall have to switch back to Penfold, crawl to the right through another hole in the wall, climb up a fourth ladder to a ninth platform and collect the fourth "DM" badge. You will then have to jump back to the left onto a tenth platform, crawl to the left through a third hole in the wall, climb up a fifth ladder to an eleventh platform, crawl to the right through a fourth hole in the wall (while watching out for three more electrical force fields, that will activate and deactivate with every second), climb up a sixth ladder to a twelfth platform and a seventh ladder to a thirteenth platform, crawl to the left out of a fifth hole in the wall and collect the fifth "DM" badge; once you've done so, you'll have to retrace your steps back down to that twelfth platform, crawl to the left through a sixth hole in the wall, walk up a staircase, and throw a third switch that freezes the water in the Weathertorium (once you've done so, the three waterfalls to its left will turn to ice, and can be used as platforms while they are frozen).
You will then have to jump back to the left onto the first two frozen waterfalls and two more platforms in turn, crawl to the left through a seventh hole in the wall, drop down to a fifth vertically-moving platform and a sixteenth platform in turn, and collect the sixth "DM" badge; once you have done so, you must retrace your steps all the way back down to the eighth platform, jump up to a seventeenth platform, walk halfway down a second staircase, jump up to a seventh vertically-moving platform, an eighteenth platform, an eighth vertically-moving platform and a nineteenth platform in turn, walk back to the left up a third staircase, jump up to two more platforms, a ninth vertically-moving one, a twenty-second one, and a horizontally-moving one in turn, and collect the seventh "DM" badge. You must then: jump up to a twenty-third platform, walk up a third staircase, jump up to a twenty-fourth platform, walk back to the left up a fourth staircase and walk onto a fourth red button to turn it green and invert the positions of three more electrical force fields (but if you walk off it again, it will invert them again) - and once you have done so, you will have to switch back to Danger Mouse, jump back up to the third vertically-moving platform, a twenty-fifth platform, a tenth vertically-moving platform and a twenty-sixth platform (in turn), switch back to Penfold, walk off the fourth button, inverting the positions of the eighth, ninth and tenth force fields in the process, switch back to Danger Mouse, jump back to your left onto the tenth vertically-moving platform, up to two more platforms and onto a pool of (now-frozen) water and a twenty-ninth platform in turn, switch back to Penfold, retrace your steps back up to the third switch, throw it again to unfreeze the water again, switch back to Danger Mouse, jump back to the left over another (now-unfrozen) pool of water to land on a thirtieth platform (the waterfall is too big to be jumped on when frozen), switch back to Penfold, throw that third switch for a third time to refreeze all the water, switch back to Danger Mouse, jump back to the left onto third (again-frozen) pool of water, onto a thirty-first platform, onto an eleventh vertically-moving platform and up to a thirty-second platform in turn, switch back to Penfold, throw the third switch for a fourth time to re-unfreeze all the water, switch back to Danger Mouse, jump back to the left over a fourth (again-unfrozen) pool of water to land upon a thirty-third platform and a fifth (again-unfrozen) pool of water to land upon a thirty-fourth platform, switch back Penfold, throw that third switch for a fifth time to refreeze all the water again, switch back to Danger Mouse, jump up to a fourth frozen waterfall, and collect the eighth "DM" badge. You then have to jump up to a thirty-fifth platform and a fifth frozen waterfall in turn, and collect the ninth "DM" badge; once you have done so, you will have to jump onto a thirty-sixth platform, a sixth frozen waterfall and a thirty-seventh platform in turn, and collect the tenth "DM" badge. You will then have to jump onto a thirty-seventh platform, drop down to the fifteenth platform, switch back to Penfold, retrace your steps back to that fifteenth platform, switch back to Danger Mouse, pick up Penfold, and throw him up to the first step of a thirty-eighth platform. You shall then have to switch back to Penfold and jump up to the second step of the thirty-eighth platform to the exit - and once you have done it you will have to switch back to Danger Mouse, and follow Penfold's path to the exit. The "MISSION COMPLETE!" text shall then be shown on the screen for what is now the eleventh time, and the duo shall then proceed onward to Episode 12, which features more water-freezing-and-unfreezing machines.
