[*at this point, the snakes that have followed you to the right side have either split up or stayed together, each with a different solution]
If the snakes stayed together, they will be in neighboring squares, typically 4-5 in the middle and only two on top. If that's the case, use the following moves:
UUDDD DDDUD UULLL LL [go open all chests]
If the snakes split up, they will be in alternating squares, typically 3 on top and 3 in the middle with a square between each snake. If that's the case, use the following moves:

*this section is where the inconsistency in snake movement will end up causing you to die or succeed. It will eventually work, but may take a few tries. It all depends on if the snake below gets stuck on another snake below it or not. If it doesn't get stuck, the moves will work. If it does get stuck, you can immediately hit C to retry the checkpoint again
