321-2-7 and your goal is to set up a vehicle that can be entirely moved up by one snake. think similarly to 3333after you collect the left side fruits, there is a new way to go up that involves the blue bird on the lowest row of the elevator
For *4/Y, are the "two ways to gain height" the same way but mirrored left to right? Or are there two unique movement patterns that allow height gain? I found the sideways "T" version but if there's another i'm not finding it
You don't need to keep the green snake's head on the platform. Even with the green snake head left of the spike, green is still recoverable after you save red and the block.
Utilizing the hint, the only first fruit I can get is fruit 2 [counting from left] with red then recovering it using green. But after that I can't find any moves.
