Once the camera has panned to Danger Mouse and Penfold's starting position, you will have to: walk to the right down a staircase, walk back to the left and collect the first "DM" badge; once you have done it, you shall have to continue walking to the right, down a second staircase (while watching out for drops of toxic waste leaking from a pipe overhead), jump diagonally up to a platform, drop down to the ground, walk up a third staircase (while watching out for an alligator), jump onto two more platforms in turn, and jump diagonally to collect the second "DM" badge and land on a sixth platform. You shall then have to retrace your steps back to the fifth platform, jump up to two more platforms, in turn, throw a switch, to activate a vertically-moving platform, drop down onto another vertically-moving platform and the ground in turn, jump over another alligator to land on an eighth platform, and collect the third "DM" badge - and once you have done so you will have to retrace your steps back to the second vertically-moving platform and jump diagonally up to a ninth platform. You now have to switch to Penfold, follow Danger Mouse's path (only instead of jumping up onto the first platform, you will have to crawl under it, and instead of jumping up to the seventh platform, you shall have to jump onto the first vertically-moving platform), drop down onto the second vertically-moving platform, jump onto a tenth platform and crawl onto a button to unlock the door above it, but if you crawl off it, it will lock it again; once you have done it, you'll have to switch back to Danger Mouse, walk through the door, and collect the fourth "DM" badge. You will then have to continue walking to the right down a fourth staircase, jump diagonally up to an eleventh platform, jump up to a twelfth platform, and collect the fifth "DM" badge - and once you have done it, you will have to retrace your steps back to the eleventh platform, drop back down to the ninth platform, walk back to the left and collect the sixth "DM" badge. Once you've done it, you shall have to continue walking to the right (while watching out for more drops of toxic waste, leaking from a second pipe overhead), climb down a ladder onto a thirteenth platform, jump to the left onto a fourteenth platform (while watching out for more drops of toxic waste leaking from a third pipe overhead), jump onto a horizontally-moving platform and jump onto a fifteenth platform to collect the seventh "DM" badge; once you have done so, you will have to retrace your steps back to the top of the ladder, continue walking to the right down a fifth staircase (while watching out for more drops of toxic waste from the second leaking pipe), jump diagonally to collect the eighth "DM" badge and land on the first step of a sixteenth platform, throw a second switch to activate a third vertically-moving platform, jump diagonally up onto the second step of the platform, walk to the right onto a fourth vertically-moving platform and drop down to the left onto a seventeenth platform to collect the ninth "DM" badge. You shall then have to jump back to the right over a gap and climb up another ladder to collect the tenth "DM" badge - and once you have done so, you shall have to retrace your steps back to the first step of the sixteenth platform, switch back to Penfold, and follow Danger Mouse's path again (but you'll have to climb a third ladder to get up to the ninth platform, and instead of jumping directly onto the first step of the sixteenth platform from the ninth one you will have to jump onto the third vertically-moving platform first). You will then have to switch back to Danger Mouse, pick up Penfold, and throw him up to the second step of the platform; once you've done so, you'll have to jump back up to the second step of the platform and walk up a sixth staircase to the exit (Danger Mouse shall again say "Come on, Penfold, catch up! We'd best stick together!" at this point), then switch back to Penfold and follow Danger Mouse's path once again. The "MISSION COMPLETE!" text will then appear on the screen again - and the duo will then proceed to Episode 3.
