The Eggs

The eggs are the bird's most desperate items they want in the game like Theme 1-8 's 'boulder". This is why the birds are angry because of the pigs who stole them. For every episode, there are three eggs other than Season's Greedings and Go Green, Get Lucky, which have one, Hogs and Kisses, 2.
