Once the camera panned over to Danger Mouse and Penfold's starting position, you will have to walk down a staircase, switch to Penfold, follow Danger Mouse's path, switch back to Danger Mouse, pick up Penfold and throw him across a gap to smash through a stack of two crates and land on a platform; once you have done so you will have to switch back to Penfold, crawl to the right through a hole in the wall and collect the first "DM" badge. You will then have to crawl back to the left out of the hole in the wall, fall down to a second platform (an air vent will blow you to the right and cause you to fall down to a third platform), crawl to the left, through another hole in the wall, throw a switch to deactivate the air vent, crawl to the left out of a third hole in the wall, climb up a ladder to the second platform and collect the second "DM" badge - and once you have done it you will have to switch back to Danger Mouse, drop down onto (currently-static) vertically-moving platform, jump up onto a fourth platform, kick a spy camera robot four times to kill it, climb up another ladder to a fifth platform, and collect the third "DM" badge. You will then have to throw another switch to activate the vertically-moving platform, fall back down onto the vertically-moving platform, jump back up onto the third and second platforms in turn, fall down onto three more platforms in turn, jump up to collect the fourth "DM" badge, walk back to the left down another staircase and throw a third switch to unlock a door above you; once you have done so you shall have to switch back to Penfold, follow Danger Mouse's path down to the eighth platform, crawl to the right through a fourth hole in the wall, climb down a third ladder to a ninth platform and jump onto two more crates in turn to collect the fifth "DM" badge (the fourth one has an electrical force field passing through it). You will now have to retrace your steps back up to the eighth platform, walk to the left onto a red button to turn it green, switch back to Danger Mouse, walk back up the second staircase and walk onto the teleporter to be transported to second part of the level (it has to be done).
Once Danger Mouse's rematerialized in front of another teleporter on a tenth platform, you will have to: jump back to the left over another red button to land on an eleventh platform, and collect the sixth "DM" badge; once you've done so, you will have to drop down to a twelfth platform, kick another spy camera robot four times to kill it, walk back to the left up a third staircase (to thirteenth platform), drop down onto a fourteenth platform, jump up onto a fifteenth platform, throw fourth switch to activate two more air vents on a sixteenth platform below you, jump up to a seventeenth platform, throw a fifth switch to unlock another door to your right, and collect that seventh "DM" badge. You will then have to drop back down to the fifteenth platform, switch back to Penfold, retrace your steps back down to the top of that fourth crate, jump onto a fifth crate, fall back down to the ninth platform, get carried up onto the fifteenth platform by the second and third air vents, switch back to Danger Mouse, pick up Penfold, and throw him up to eighteenth platform - and once you've done so, you have to switch back to Penfold, walk through the second door, crawl to the right through a fifth hole in the wall, climb up fourth ladder, to nineteenth platform, crawl to the right, out of sixth hole in the wall, throw a sixth switch to unlock a third door below you, crawl back to the left, out of a seventh hole in the wall, drop down onto a twentieth platform, throw a seventh switch to activate three more air vents on a twenty-first platform below you, be carried up to a twenty-second platform by the fourth, fifth and sixth air vents, and walk to the left to the exit. You'll then have to switch back to Danger Mouse, retrace your steps back to that tenth platform, walk through the third door, collect the ninth "DM" badge, jump up to the halfway point of a fourth staircase, walk up it to a twenty-third platform (ignoring an eighth switch that will deactivate the fourth, fifth and sixth air vents again), and collect that tenth "DM" badge; once you've done so, you'll have to switch back to Penfold, retrace your steps down to that twelfth platform, switch back to Danger Mouse, fall back down to that twelfth platform, pick up Penfold, and throw him up to the tenth platform. You now have to switch back to Penfold, walk onto that second red button to turn it green, switch back to Danger Mouse, jump back up onto the tenth platform, and walk back onto that second teleporter to be transported back to the first part of the level (again, it must be done, and things may get a bit confusing at this point).
Once Danger Mouse's rematerialized in front of the first teleporter on the eighth platform again, you'll have to jump back up to the seventh platform, a twenty-fourth platform and the fourth platform in turn, get carried up onto the twenty-second platform (by the fourth, fifth and sixth air vents), and walk back to the left to the exit; once you do it, you'll have to switch back to Penfold, retrace your steps back up onto the twenty-second platform, and walk back to the left to the exit. The "MISSION COMPLETE!" text shall now appear on the screen for the fourteenth time - and the duo will then proceed to Episode 15 (which will see Penfold's shield automatically activating in a zero-gravity environment, and giving him the ability to move and jump with it).
