Once that camera has panned over to Danger Mouse and Penfold's starting position, you will immediately have to switch to Penfold, walk to the left up a staircase to a platform, crawl to the left through a hole in the wall, climb up a ladder to a second platform, throw a switch to lock a door behind you (it will also automatically cause Penfold's shield to activate, and a second door to unlock in front of him), walk through the second door, multi-jump up to a third platform and collect the first "DM" badge; once you have done so, you will have to multi-jump to the right onto to the second step of a fourth platform and a fifth platform in turn, and collect the second "DM" badge. You shall then have to retrace your steps back down onto the second platform, and walk onto a red button to turn it green and unlock a third door below you (but if you walk off it again, it shall lock it again) - and once you have done it, you will have to switch back to Danger Mouse, jump up to a sixth platform, walk through the third door and down another staircase, jump up to three more platforms in turn, throw a second switch to open a trap door above you, drop down to a tenth platform, jump back to the left onto an eleventh platform and collect the third "DM" badge. You must then drop down to a twelfth platform (an air vent will blow you to the left, causing you to drop down to a thirteenth platform), throw a third switch to deactivate the air vent, drop down to a fourteenth platform, use Danger Mouse's grappling hook on the platform-mounted anchor, abseil to the left over the rope, and collect the fourth "DM" badge; once you have done so you shall have to drop down to a fifteenth platform, walk back to the left up a third staircase to a sixteenth platform, jump up to a seventeenth platform, walk up a fourth staircase to an eighteenth platform, jump onto a vertically-moving platform and that starting platform, in turn, switch back to Penfold, multi-jump up to a nineteenth platform (relocking that third door in the process), walk up a fifth staircase to a twentieth platform, fall down through that (now-opened) trap door onto a twenty-first platform, drop down to a twenty-second platform (while watching for a spy camera robot) and collect the fifth "DM" badge. You'll then have to multi-jump back up to the twentieth platform, and multi-jump up (while watching for another spy camera robot) to collect the sixth "DM" badge - and once you have done so you will have to land on twenty-third platform, walk down a sixth staircase, onto a twenty-fourth platform, drop down onto a twenty-fifth platform, throw a fourth switch to deactivate another air vent, multi-jump up to twenty-sixth platform, walk up a seventh staircase, to a twenty-seventh platform (and back down an eighth one to that twenty-sixth platform again), fall down to a twenty-ninth platform, and collect the seventh "DM" badge. You'll then have to retrace your steps back to that first red button, walk onto it to turn it green and unlock the third door again, switch back to Danger Mouse, retrace your steps back down to the twelfth platform, walk down a ninth staircase onto a thirtieth platform, switch back to Penfold, retrace your steps back up to the first switch and then throw it for a second time to relock the second door (this time, it shall automatically cause Penfold's shield to deactivate, and the first door to reunlock).
You'll then have to retrace your steps back down to that starting platform, drop down onto the vertically-moving platform and the eighteenth platform in turn, switch back to Danger Mouse, retrace your steps back to that eighteenth platform, pick up Penfold, and throw him over a gap to smash through a stack of two crates and land on a thirty-first platform; once you have done so you will have to drop down to the thirteenth and thirtieth platforms in turn, climb down another ladder, to a thirty-second platform, crawl to the right through another hole in the wall, throw fifth switch to unlock fourth door above you, switch back to Danger Mouse, retrace your steps back down to the thirtieth platform, walk through the fourth door, switch back to Penfold, retrace your steps back to the first switch, throw it once again (to relock the first door, automatically reactivate Penfold's shield, and reunlock the second door), retrace your steps back down to the twenty-second platform, drop down to a thirty-third platform, and walk onto another red button to turn it green and unlock a fifth door below you (but for a second time, if you walk off it again, it'll lock it again). You will then have to switch back to Danger Mouse, walk through the fifth door, drop down to a thirty-fourth platform, kick a toad guard three times to kill him, jump up to a horizontally-moving platform and two more platforms in turn, and collect the eighth "DM" badge - and once you've done so, you will have to use Danger Mouse's grappling hook on another wall-mounted anchor, abseil to the left over the rope, drop down to a thirty-seventh platform, jump up to two more platforms, another vertically-moving platform and a fortieth platform in turn, use Danger Mouse's grappling hook on a third wall-mounted anchor, abseil to the right over the rope, fall down onto forty-first platform, walk down a tenth staircase onto a forty-second platform, jump up onto two more platforms in turn, and collect the ninth "DM" badge. You will then have to: jump up to a forty-fifth platform, throw a sixth switch to open another trap door to the right of you, drop back down to the forty-second platform, switch back to Penfold, retrace your steps back up onto the twenty-ninth platform (relocking the fifth door again in the process), jump up to forty-sixth platform, drop down through the second (now-opened) trap door onto forty-seventh platform, drop down onto two more crates in turn (while watching for a third spy camera robot), and drop down to collect the tenth "DM" badge and land on a forty-eighth platform; once you do so, you will have to jump back to the left, onto a forty-ninth platform, multi-jump up to a fiftieth platform, throw a seventh switch to lock a sixth door behind you (it will also again automatically cause Penfold's shield to deactivate, and a seventh door to unlock in front of him), walk through the seventh door, jump onto a third vertically-moving platform and the forty-second one in turn, pick up Penfold, and throw him up to a fifty-first platform in order to land upon a third red button and turn it green (but, if Penfold doesn't land on the button, you will have to switch back to him and walk onto it). You will then have to jump up to the fifty-first platform and walk onto the teleporter to be transported to another part of the level, like in the previous one - and once Danger Mouse 's rematerialized in front of another teleporter on a fifty-second platform, you will have to walk onto a fourth red button to turn it green, switch back to Penfold, and walk onto the first teleporter to be transported to the second part of the level. Once Penfold has rematerialized in front of second teleporter on the fifty-second platform, you'll have to fall down onto a fifty-third platform, switch back to Danger Mouse, follow Penfold's path, then pick up Penfold and throw him up to a fifty-fourth platform; once you have done so, you will have to jump up to the fifty-fourth platform and walk down an eleventh staircase to the exit. You will then have to switch back to Penfold, and follow Danger Mouse's path to the exit - and the "MISSION COMPLETE!" text will now appear on the screen for a fifteenth time. The duo shall now proceed to Episode 16, which is a boss level that sees them facing off against Baron Greenback himself for the first time since he hired Victor and Hugo to steal their Mark III car (on Bunglers in Crime in 1992).
