He and his momma, Bonnie, were getting sick and tired of living in that pen. After a couple weeks of bandage changes daily, then every other, then every third day, the wounds on his legs were finally healed enough to go uncovered.
Obviously, those injuries weren't slowing Buzz down in the least. He was dancing and prancing and hopping all over the place.

Here is the album with all of the pictures from Buzz's saga. Be warned that some of the wound pictures are rather gory.
