Oliver was furiously shoving snow in front of him, trying to pile it up as high as he could. He did it as fast as he could, trying to get a lot of snow piled up before the girls launched their next attack. The pile didn't stretch very far to either side. If Sabbath wanted protection in front of him, he would have to work on his own.

While he was working, Oliver also took some time to pause and make snowballs. He threw three over toward the girls, one aimed toward each of them. He knew he wouldn't be able to get his wall built before they launched a counter-attack, but he could at least try. But he also took some time to pack snowballs and keep them next to him. So he didn't have to make a new one every time he wanted to throw one.
