Hey everybody. I finally got my video uploaded on Youtube. So here is a video tutorial on how to beat mission 7. If the video says it’s no longer available, just double click the video. 
~Text Version~ (15 easy steps!)
1. Start the mission by answering everything G says.
2. Now click the screen that G tells you to click and watch the video.
3. After that go to the right of your screen and look at the invention cabinet. Click the middle lock. Now use your code and put in “Key”.
4. Now when the lock opens, grab the magnet and put it into your inventory. Now look to your right and go inside of the gadget room. Look around until you shelves of items. Grab the lifeguard ring and put it into your inventory.
5. Go to the Iceberg and look around until you see a spring in the water. Take the magnet out of your inventory and put it up to the spring and click it. No add the spring and magnet into your inventory.
6. Use your map and go to the Town. Now talk to the green penguin until he gives you the blueprints of the missing wheel for the clock tower.
7. Go to the Beach by using your map and grab the green bucket between the two penguins. Then go to the Snow Forts and fill the bucket with snow. Now go to the Dock. Look around and you should see the blue team there. They will challenge you to a game. Play the game. When you beat it, grab the target from them and put it into your inventory. Now give the blue team the lifeguard ring.
8. Go to the Pizza Parlor and garb the music notes next to the piano. Then go to the Stage and click on the piano. Put the notes on the stand and start playing the notes. If you play all these notes correctly, a yellow puffle will appear.
10. Go back over and the puffle will jump and follow you. First, give him the blueprints of the missing magnet. Then give him the bucket of snow. He will start building the wheel that goes to the clock tower. When the puffle is done, add the wheel into your inventory.
11. Now go to the HQ and go inside the gadget room. Look for something that says “Test Chamber”. Now look where it says “Place object here”. Put the spring there. Now push the red lever and the spring should go inside. Now push the fire icon. The ice should melt away off it. Now push the red lever again, and when the spring comes out add it to your inventory.
12. Now do the same with the clock tower wheel except push the snow icon. Now put the wheel into your inventory. Now go to the Snow Forts. Look where the broken clock tower is and click the arrow leading to it. You should be looking behind the clock tower.
13. Take the wheel out of your inventory and put it right in the middle of the machine. Now look where the spring is to the right of the machine. Put the spring in your inventory on the opposite side of the other, where it is supposed to be. Now take the target out of your inventory and put it in its place.
14. Go back to the Snow Forts and check your inventory. Click your spy phone. The polar bear is calling. Read everything he says. Now G should come out and congratulate you.
15. Now end the mission by receiving your medal and gift. Now click End Mission. And that’s it! You just beat mission 7!
