Best Solution

The image below is a demonstration of how to win the episode. It is the best solution that I have come up with but if you come up with a better solution then please let me know.

Start off by moving the green crate to the right. The red crate is moved up, left, up, and finally right to the final position. We return to the green crate moving it up, right, down, left and finally up to the final position. Blue only needs to be moved to the left to be placed in its' final position.
