How to get Medium Badge: Have both walls filled with 6 Sentinels, 5 Buzzsaws evenly spaced out, the roof covered with Turrets, the floor covered with Launchers and Mines, and all valves open and at least at lvl 10. Hit a turtle (do something while you wait) and come back later. If at 100,000x combo or more, hit the menu button and ta-daa, Medium Badge. Hope this helps! :D
When you are flying (and you don't destroy a thing) and you fly over the wall and it hits the Dodo's house, your destruction should go up for destroying the Dodo's house.
