The mission starts in the gadget room:

1. Talk to G – an earthquake will happen every so often
2. Pick up the flying Fedora Hat hanging behind G
3. Go to the Dock and talk to Herbert when he comes out of the ground
4. When he leaves grab the lamp Klutzy drops (optional as you can use the Night Vision Goggles instead)
5. Follow the map Klutzy snapped in half as it flies into Town
6. One will get stuck on the Night Club sign and one will continue to blow away towards the Snow Forts – you can’t grab them just yet
   
7. Go into the Coffee Shop and help pick up the cookies that fell on the ground. The penguin will offer you a cookie when your finished, put it in your inventory
8. Go outside and put the fedora hat on the green puffle. Then feed him the cookie so he can fly high enough to get you half the map – put it in your inventory
9. Follow the other half of the paper to the Snow Forts. It is stuck in one of the flag poles. Free it by clicking on it and let it fly into the Plaza
10. It will get stuck in a guy’s newspaper. Talk to him. He will mention he wants a pizza
11. Go in the Pizza Parlor and get a pizza, then go outside, give it to him and ask for the newspaper
12. When he gives you it, take the map piece out of it (put the newspaper in your inventory then click on it to get the map) and stick to two halves together: you can now find your way around Herbert’s tunnel
13. Grab the following equipment first:
14. Some tent pegs from the Sport Shop near the door
15. A net from the pile outside the Lighthouse
16. Some balloons – the orange penguin in the Lighthouse will give youa box
17. The hammer that’s hanging on the wall in the Gadget Room (to the right of G)
18. A helium tank from the Gadget Room to the left of the door into the HQ (ask G before you taking it)
19. Then take a balloon out of the balloon box and fill it up with helium
20. Go to the Town
21. Use the inflated balloon to lift up the Gift Shop (yes, really!)
22. Quickly put the net under the Gift Shop, then add the pegs around the net and use the hammer to plant them into the ground
23. This will fix the Gift Shop so you can safely continue through the tunnel
24. Go to the tunnel (to the left of Town and towards the lighthouse, go in tothe hole in the ground)  and find your way around using your map (left means the tunnel on the left, right the one on the right – use your night goggles to see where you are going)
25. When you reach the tunnel under the Gift Shop you will see the drill Herbert was in.
    Use the spanner from your spyphone to unscrew the gear at the back.
    Put the gear in your inventory and carry on through the hole into the Boiler Room (towards your left)
26. Talk to Herbert. He will break the boiler in frustration & run away
27. G will tell you to fix the boiler (the spyphone will ring)
28. Click on the boiler and use the plumbing tubes to connect the top left-hand pipe to the bottom right-hand pipe to fix it (click on any two that you want to swap around)
29. When you fix it G will tell you to meet him at the HQ (your spyphone will ring)
30. Go to the HQ & talk to G
31. Give him the gear
32. G says that the next mission will be about catching Herbert
33. Get the medal & the cool gear

That’s it! Well done!
