Mine and Dine 15-12 is the 12th level of the first episode of Mine and Dine. There is a Golden Egg called Golden Egg #23 in the top-right in this level. See this page for more information to get that Golden Egg.
Loft the Blue bird to kill the middle tower, causing the bird to ricochet into the stalactite above and one of the ropes holding the suspended pig. Fire the Boomerang bird to a direct hit on the far-right tower. Lob the Black bird to land between the first and second roof, just left of the TNT. Use the next two Yellow birds and the Pink bird as necessary to finish the level.
