Use your imagination.
They would probably be pretty careful about making you walk a wooden plank.
And they'd eat a lot of blood oranges. (To avoid scurvy and thirst.)
Then they'd get upset when they learned that blood oranges don't have real blood in them.
(Just like bacon bits don't have real bacon in them. Or blood.)
Then they'd kill whoever misinformed them about the blood oranges, and drink THEIR blood.
And everyone would be happy. Except for that dead guy.
