Once the camera has panned over to Danger Mouse and Penfold's starting position you shall have to jump up to the second step of the platform you are standing on, drop down to a second platform, jump back to the left onto a third platform and collect the first "DM" badge; once you have done so, you will have to drop down to a fourth platform, throw a switch to move a mirror to the left (this diverts the first beam of light downward), jump onto a fifth platform and collect the second "DM" badge. You'll then have to drop back down to the fourth platform, a sixth platform and a seventh platform in turn, and collect the third "DM" badge - and once you've done so, you will have to switch to Penfold, and follow Danger Mouse's path (only instead of jumping back to the left onto the third platform, you will have to drop down to an eighth platform, walk to the left down a staircase, and drop down onto that seventh platform). You will then have to switch back to Danger Mouse, pick up Penfold and throw him back to the left to smash through a stack of three boulders; once you have done so, you'll have to switch back to Penfold and throw a switch to move another mirror downwards (it will divert the first beam of light to the right, upward and to the right again, killing two temple guardians as it hits them). You'll then have to switch back (to Danger Mouse), drop down to the ground, switch back to Penfold, follow Danger Mouse's path, switch back to Danger Mouse, pick up Penfold and throw him to the right to smash through another stack of four boulders - and once you have done so, you will have to switch back to Danger Mouse, drop down to the second step of the ground, pick up Penfold and throw him over a pool of water to land on a ninth platform (if he lands in the pool of water, he will regenerate back on the second step of the ground with one less energy bit). You must now switch back to Penfold, jump onto a tenth platform, and throw a third switch to drain the aforementioned pool of water (once it has been completely drained away, Danger Mouse will say "Aha! I see another switch that had been hidden by the murky water!").
You will then have to drop down to the now-exposed third step of the ground and collect the fourth "DM" badge; once you have done so, you will have to jump back to the left over an (already-opened) trapdoor with what's left of the pool under it, throw the (now-exposed) fourth switch to move a third mirror downwards (it will divert the second beam of light downward), and collect the fifth "DM" badge. You will then have to switch back to Danger Mouse, drop down to the third step of the ground, pick up Penfold and throw him back up to the second step of the ground (this may take quite a few tries) - and once you have done so, you will have to jump back up to the second step of the ground, pick up Penfold and throw him back up to the first step of the ground. You shall then have to jump back up to the first step of the ground, pick up Penfold and throw him back up to the seventh platform (this may, again, take quite a few tries); once you do so, you shall have to jump back up to the seventh platform, pick up Penfold and throw him back up to the eighth platform. You'll then have to jump up to that eighth platform, walk up the staircase, drop down to the second step of the platform and three more platforms in turn, and collect the sixth "DM" badge - and once you've done so you'll have to switch back to Penfold, follow Danger Mouse's path (only instead of dropping down to the twelfth platform, you'll have to jump onto two clouds in turn) and collect the seventh "DM" badge. You'll then have to jump onto a fourteenth platform, crawl to the right and collect the eighth "DM" badge; once you have done so you will have to retrace your steps back to the second step of the eighth platform, switch back to Danger Mouse, follow Penfold's path, pick up Penfold and throw him onto a fifteenth platform. You then have to jump up to the fifteenth platform, pick up Penfold, and throw him up to a sixteenth platform - and, once you do this, you must jump up to a seventeenth platform, jump over a third temple guardian (remember they cannot be killed by kicks) and throw a fifth switch to move a fourth mirror to the left (it shall divert the third beam of light to the left). You must now jump back over the 3rd temple guardian and onto the fifteenth platform, pick up Penfold, and throw him up to a third cloud; once you've done so, you'll have to switch back to Penfold, and jump up to an eighteenth platform. You will then have to switch back to Danger Mouse, jump onto a nineteenth platform and the eighteenth one in turn, pick up Penfold, and throw him up to twentieth platform - and once you have done so, you'll have to switch back to Penfold, walk to the right, and collect the ninth "DM" badge. You will then have to walk up another staircase and throw a sixth switch to move a fifth mirror to the right (it will divert the third beam of light downward, killing the third temple guardian when he walks into it); once you have done so you will have to throw the switch again to return the fifth mirror to its original position (Danger Mouse will say "We did it! That's the last of the light shafts, let's get to that door and track down that artifact!" at this point to inform you the door has been opened by the beams).
You will then have to retrace your steps back to the now-opened door on the first step of the eighth platform, switch back to Penfold and follow Danger Mouse's path; the "MISSION COMPLETE!" text will now appear on the screen for the sixth time. The duo will now proceed onward to Episode 7 which can be described as a "sort-of-boss" level and must be finished with Penfold alone - but if he can defeat the enormous Toad God, he will gain a shield.
