Hey, can you please give another hint for #3?
I've figured out how to stack blue on top of yellow, get the fruit, and have deduced that I need to go to the right side of the screen to get both birds to the exit. The problem I am having is that I have no idea how to get the yellow bird in position for them to bring blue and themselves to the exit, as every time I try to get them over, they just get stuck. Any tips?
