Fun fact: this was a real execution method used in ancient Rome called poena cullei.

Known in English as the "penalty of the sack" (as stated in the artist's commentary), the death penalty involved placing a person in a sack alongside a viper, a monkey, a rooster and a dog, and then throwing them into a body of water. A very awful and very specific way to die lol

Isn't that just the Boo Box from Hook?
