Final chest

Assemble your wood blocks for the order and knock on the chest

“Arrrr… ye stand before the final chest, but this one won’t open with just any old knock.
If ye’ve gathered all the pieces o’ me puzzle, ye know the order.
The markings on this very chest’ll tell ye how many times to knock for each.
Do it right, in the right order—and the final treasure’ll be yours.
But mess it up… and ye’ll be knockin’ like a fool for eternity!”
