The Cannonless strategy. Just remember to take it slow at first. You’ll get faster the more you do it.
Below are the inputs for the actual trick.
This was taken from toastrider91‘s video description:
“Ledge grab next to plank
Press A to get up from ledge grab
Backflip C-left twice
Press B to punch (make sure you let the punch animation finish before you walk down or he will turn first and it will be less consistent.)
Hold down very slightly to slowly walk and ledgegrab
Reset camera by pressing c-right then c-left
Hold up to slowly climb up, c-up, then when you see climbing animation, hold straight down.”
