If you aim on the left side of the screen and just stay there, you'll hit the people with more ease. And, you can hit them more than once. You can get that guy in red or the girl in blue at least 3 to 4 times each time they pop up. Now, getting that little green guy w/ the green hat is already hard enough. But, if you start throwing as he pops up, you can easily get 2 shots on him. Take your time. There's no time limits....just limits on hitting Santa and how many snow balls you get.
