To get 3 stars on Poached Eggs Level 1-10, follow these instructions.
1. Level 10 of the first theme will be our first encounter with the small blue birds.
2. Make the projectile really high and watch the launched bird multiply into three. Two of the birds will hit the stack of ice blocks while the other one will hit the stone post of the structure placed on a higher mound and will roll on the ice post on the lower structure.
3. Aim the next bird on the remaining ice blocks. Again the blue bird will multiply.
4. This time aim a little lower than the previous ones and hit the stone post of the higher structure and the ice post of the lower structure.
Here is a video walkthrough for Level 1-10
