Our strategy for Ragnahog level 14 is shown in the video below. The three birds we use get one star each on their way to 111310.
The first blue is lofted at about 45 degrees to the corner of the ice structure in the middle, a late activation concentrates the force of the three siblings to break and bend the ice and structures to the right. Hopefully you will release the caged bird at the far right with this one. The next blue is thrown a bit lower ot the corner of the second stone structure with another late activation, leaning it over. Now, throw Stella in a high lob to come down on the rune stone at the junction of all the stone planks remaining in the second structure, picking several up and sending them right while knocking over the structures to the left. The Bomb bird is released and all pigs are deceased, so now you three birds on deck for a 30K bonus.
