The earliest level this can be obtained in is 'Past Due'. Shortly after starting the level you will go through a subway tunnel. After you get through the subway tunnel, a fight scene will be triggered. Once the all enemies have been defeated, you will need to use Feedback to destroy the metal door blocking your path. As soon as you get through, in the hallway there will be 8 crates in a corner. Simply use Feedback or a bigger alien form jump in the air and press to preform a heavy smash attack to destroy all the crates.
If you missed this in 'Past Due', you will have another chance in 'That was then...'. In the beginning of the level you will be in a fight scene. Once you have defeated the enemies continue forward, you will come to the end of the dock (where you will have to use Four Arms to climb). Instead of climbing, jump forward and there will be around 18 crates. Again use a bigger alien form, jump in the air and press to preform a heavy smash attack.
