Here is our guide to get 3 stars on Poached Eggs Level 2-18.
1. There are three floating structures that enclose 3 pigs and there are 2 additional pigs on the ground. Aim the first bird at the leftmost floating structure.
2. Launch the white bird over the remaining pig on the ground and have it drop an egg on it.
3. Aim the third bird (yellow) on the remaining stone stick in the middle floating shelf. The bird will bounce off and will hit the neighboring structure on the right.
