Golden Egg #37 is located on level 1-13 of Angry Birds Seasons Back to School. There are two steps required to obtain this Golden Egg. First fire Terence low so he bounces off the base of the structure and bounces back into the textbook hanging from the rope. After you destroy the textbook a stone barrier will pop up on the left hand side of the screen behind the slingshot. Now to get the golden egg gently lob big brother so he slowly rolls down, hits the stone barrier, and bounces back into the egg.
To obtain the star on the level thread the yellow bird through the apple-lined gaps and into the TNT on the right hand side. This should set off a wave of destruction and earn you your star.
