I guess the only way to complete Level 3 easily would be to level up most of your plants to Level 3, and watch Intellectual Games playthrough of it, then do what he did. The main trouble is upgrading your plants. Some puzzle pieces can only be obtained from Level 3 events which makes it more of a pain.

Once someone has upgraded their plants, they can finish the levels on their own easily.
