Our strategy for Easter Eggs level 2-1 (formerly level 1-16) is to loft the Yellow bird under the hollow stone square in the top-right, aiming to detonate the TNT at the right of the structure. Lob the Black bird to land between the first two roofs, blowing the structure apart. Use the White bird if necessary to clear the level. The score in the video below is 96,480.
Note: In a recent update, the level numbers were changed from Level 1-16 to Level 2-1.
