Golden Egg #87 is hidden on Ragnahog Level 12. The video below is in two parts, first we get the egg and then we clear the level.
The egg is in the bottom right corner of 1-12, the video uses all the birds to get to it, but pretty much any shot that gets the bottom right pig to roll right and be propelled left should do. Once you get to the egg level, simply throw a Bomb Bird to impact the ramp below the stone and manually activate. The force of the blast should propel the stone up the ramp, off the backboard, and through the net to the pig. Instead of a rebound, he gets smashed! The final score in the video is 36810. Who knew the Vikings invented Basketball!
