Hi, I did read it. With the spike added, I keep ending up with the same two outcomes. I'm wondering if I need red bird's head, the block and green bird's tail all stacked on the top of the blue bird at once to push the block, like the third picture.
no, my hint indicates this isn’t what you are trying to do. the hint references another level with the same type of key move you need, did you understand what i was referring to in that other level?
