Once the camera has panned down to Danger Mouse's starting position, you'll have to jump up to two platforms in turn, and collect the first "DM" badge; once you've done so, you shall have to drop back down to the ground, jump over any robo-bombs that may be walking towards you (there are an infinite amount of them, and when they come to a ladder, they shall drop down to the platform below, but if one hits Danger Mouse it will explode into a fireball), climb up a ladder to a third platform, jump up to a fourth platform, throw a switch to unlock a door above you, drop back down to that third platform, jump over any more robo-bombs that are walking towards you, walk up a staircase (the second half-ladder is too short for Danger Mouse to jump up to), jump up to a vertically-moving platform and onto a fifth platform in turn, use Danger Mouse's grappling hook on a wallmounted anchor, abseil to the right over the rope and collect the second "DM" badge. You will then have to drop down to a sixth platform, walk to the right through the door, jump over any more robo-bombs that are walking towards you, jump up to a third half-ladder, and climb up it to a seventh platform, jump over any more robo-bombs that are walking towards you, climb up a fourth full ladder and collect the third "DM" badge - and once you have done this you shall have to climb back down the ladder, jump over any more robo-bombs that are walking towards you, walk up another staircase and jump up to collect the fourth "DM" badge. You will then have to walk to the right up a third staircase, to an eighth platform, jump over any more robo-bombs that are walking towards you, walk up a fourth staircase, use Danger Mouse's grappling hook on a second wall-mounted anchor, abseil back to the left over the rope, fall down to a tenth platform and collect the fifth "DM" badge; once you have done so you will have to drop back down to the third staircase, retrace your steps back to the tenth platform (while again jumping over any more robo-bombs that are walking towards you, but this time, you can jump up to and climb up the fifth half-ladder to get back up to there), walk to the left up a fifth staircase (the sixth half-ladder's too short for Danger Mouse to jump up to) and collect the sixth "DM" badge. You will now have to use Danger Mouse's grappling hook on a third wallmounted anchor, abseil to the right over the rope and collect the seventh "DM" badge - and once you have done so you will have to drop back down to the tenth platform, retrace your steps back to the top of the fifth staircase, walk to the right up a sixth staircase to an eleventh platform (Danger Mouse will say "Nearly there, Penfold! You'll pay for this, you robot fiend!" at this time).
You'll then have to walk up a seventh staircase and collect the eighth "DM" badge; once you've done it you will have to drop down to a twelfth platform and collect the ninth "DM" badge. You will then have to use Danger Mouse's grappling hook on a fourth wallmounted anchor, abseil to the left over the rope and collect the tenth "DM" badge - and once you have done this you will have to drop back down to the tenth platform, retrace your steps back to the eleventh platform and jump up to and climb up a seventh half-ladder to a twelfth platform (Danger Mouse shall say "Up there, the release lever for the trap door that robotic Colonel is perched right over." at this time). You will now have to climb up an eighth ladder to a thirteenth platform and throw another switch to open the trap door (the fake Colonel K' will say "What's this, what's going on? Noooooo!" at this point, then fall through the trap door and off the bottom of the level as any robo-bombs that are still on it automatically explode); once you've done so the game will automatically switch to Penfold as his cage disappears (he'll say "Cor, Chief! You did it!" at this point to which Danger Mouse will reply "Yes! Yes, I did rather. Phew! Now, to free the real Colonel and get back on the trail of Greenback!", but Greenback will say, "Dratted mouse, you'll regret ever tangling with my schemes!"). You'll then have to drop down to the twelfth platform and walk to the exit - and once you have done so you will have to switch back to Danger Mouse, walk to the left down an eighth staircase and through another door (it got unlocked when Penfold's cage disappeared), drop back down to that twelfth platform, and follow Penfold's path to the exit. The "MISSION COMPLETE!" text will now appear on the screen for a tenth time - and the duo will then proceed to Episode 11, which is based in Baron Greenback's Weathertorium, a building wreaking havoc on the climate by turning it into a giant pond.
