Golden Egg #5 is located on level 7 of Angry Birds Seasons Hogs and Kisses. Zoom out and you’ll see there is a Golden Egg below the bird platform. You can get it by launching a White bird backwards and dropping the egg bomb so it lands right next to the egg.
To obtain the star on the level, simply fire the Red bird into the TNT immediately in front of the slingshot. The Rube Goldberg machine may occasionally jam itself, but most of the time, you should earn the star.
