I did an angry birds theme for Ben's birthday even though it was just us
I blew balloon sup in promary colors and hung them upside down form the ceiling in clusters in the kitchen
you could also buy angry birds plushies in all the different colors and types of birds and place them randomly on the food table
I also used just a plain primary color bucket {perfect time of year for those at the $1 store} and printed a bunch of things frm Meg and Traci's kit and placed them on wodden skewers as a centerpiece! {can you see the balloons hanging from the ceiling}....
you could make up little place cards food descriptons that have something to do with pigs or birds
Space Balls {for meatballs...sicne there is Angry Birds Space now}
Pigs in a Blanket
Bacon Bites
Pig Punch or Bird Bath for a punch bowl
