This is so awesome!
I think this is one of your best submissions, if only because I love those groundcats. When I first saw the title, I thought it was going to be a parody of Groundhog Day. I know it was too late for that. Besides, it's Martin Luther King Jr.'s birthday on the day it was submitted. I was so happy to see those crazy guys at the end of the cartoon. Michael Swain is fantastic as always. I also love how the birds have so much detail put into them.
There could have been some more action, but it was still hilarious. I have never played the "Angry Birds" game on iPhone. This is mostly because I do not have an iPhone of any kind. Continue to make awesome stuff like this as wacky as ever. It was just so fun to watch because of how the colors were so wonderfully bright.
