Once the camera pans over to Danger Mouse and Penfold's starting position, you'll have to walk to the right, climb up a ladder and jump diagonally up to a platform, at which point Colonel K' will reappear to say: "These pads disable all the trip wires in the Museum - but only while you're standing on them."; once you've walked onto the red button to turn it green and disable all the trip wires, you will have to switch to Penfold, follow Danger Mouse's path (only instead of jumping diagonally up to that first platform, you must crawl to the right under it, walk down a staircase, then collect the first "DM" badge). Once you have done so, you shall have to walk up another staircase and throw a switch (to activate a horizontally-moving platform), retrace your steps back to the top of the ladder, switch back to Danger Mouse, drop back down to the ground (reactivating the trip wires in the process), pick up Penfold, and throw him up to the first platform (but if Penfold does not land on the button, you will have to switch back to him and walk onto it, to turn it green and disable all the trip wires again) - and you then have to switch back to Danger Mouse (if Penfold didn't land on that button), walk back to the left and jump diagonally up to another platform, at which point Professor Von Squarkencluck shall appear to say "Aha! Our blueprints tell us zat's one of the 6 switches you need to throw to get ze lift working. Activate all 6, quick as you can!". Once you have thrown the elevator switch you will have to walk to the left and collect the second "DM" badge; once you've done so you shall have to drop back down to the ground, jump back up to the first platform, pick up Penfold and throw him back to the left to land on the second platform. You will then have to switch back to Penfold, climb up another ladder to a third platform, crawl to the right over a second red button to turn it green momentarily (because Danger Mouse is still standing on the first button, it has no effect on the trip wires), jump onto a vertically-moving platform, a fourth platform and another vertically-moving platform in turn, throw the second elevator switch and collect the third "DM" badge - and, once you've done so, you will have to retrace your steps back down to the fourth platform, jump onto a fifth platform, drop down to collect the fourth "DM" badge and land on a sixth platform. Once you've done so, you shall have to drop back down to the button on the first platform, switch back to Danger Mouse, jump diagonally up to the sixth platform, and a seventh platform, in turn, throw the third elevator switch, drop down to the horizontally-moving platform and collect the fifth "DM" badge; once you have done so, you shall have to jump diagonally up to an eighth platform, throw another switch to activate a third vertically-moving platform, jump diagonally up to a ninth platform, and collect the sixth "DM" badge. Once you've done so, you shall have to jump up onto a tenth platform, throw the fourth elevator switch and collect the seventh "DM" badge - and once you've done it, you will have to walk back to the left, jump diagonally upward, to land on an eleventh platform, walk up a third staircase and over a third red button to turn it green momentarily (because Penfold is still standing on the first button, it will again have no effect on the trip wires!), drop down onto a twelfth platform, throw the fifth elevator switch, jump diagonally up to two more platforms in turn, and collect the eighth "DM" badge. Once you've done so, you'll have to retrace your steps back to the tenth platform, fall down onto the third vertically-moving platform and collect the ninth "DM" badge; once you've done so, you shall have to walk to the left, onto a thirteenth platform, and kick a toad guard three times to kill him (this is the first time Danger Mouse will have to deal with Greenback's henchmen since his final ITV appearance on Bunglers in Crime, in 1992). Once you have done so, you will have to walk back to the right onto the third vertically-moving platform, drop down to a fourteenth platform and kick another toad guard three times to kill him - and once you have done so, you'll have to activate the sixth elevator switch. Once you've done so, Colonel K' shall reappear to say "Good show, DM! The museum's lifts are working again, get your tail up there to the top floor and secure that doodad!"; you will then have to retrace your steps back to the first platform, pick up Penfold, and throw him back up to the sixth platform. You will then have to jump back up to the sixth platform (but because you are jumping off the button after Penfold is no longer on it, you will touch a once-again-reactivated trip wire in the process and unlock all the doors in the museum, so if any additional toad guards who were previously trapped behind the doors approach you, you will again have to kick them three times to kill them), pick up Penfold, and throw him back up to the fifth platform; once you have done so, you will have to jump back up to the fifth platform, pick up Penfold and throw him onto the seventh platform. You'll then have to jump back over to that seventh platform, pick up Penfold, and throw him over to the fourteenth platform - and once you have done so, you will have to drop back down to the first platform, walk onto the button to turn it green and disable all the trip wires once again, switch back to Penfold, climb down a third ladder, crawl to the right and collect the tenth "DM" badge. Once you've done so, you will have to throw a third switch to activate a fourth vertically-moving platform, climb up a fourth ladder, jump up onto the third vertically-moving platform, a fifteenth platform, and the fourth vertically-moving platform in turn, jump back to the left onto a sixteenth platform, then walk onto a fourth red button to turn it green, and disable an electrical force field. You will then have to switch back to Danger Mouse, retrace your steps back up to the tenth platform, follow Penfold's path (only instead of jumping back to the left onto that sixteenth platform, you will have to jump onto a seventeenth platform, and walk onto a fifth red button to turn it green, but because Penfold is still standing on that fourth button, it has no effect on the electric force field); once you've done so, you must switch back to Penfold, jump back onto the fourth vertically-moving platform (because Danger Mouse still stands on the fifth button, it'll again have no effect on the electric force field), jump onto the seventeenth platform and walk into the elevator. You will then have to switch back to Danger Mouse and follow Penfold's path into the elevator (reactivating the electrical force field in the process) - and that "MISSION COMPLETE!" text shall then appear on the screen for a third time. The duo will then proceed to Episode 4 (which features Greenback's crow assistant, Stiletto Mafioso).
