• The truth behind it all: Throughout the episode, it appeared to the audience that Cub was inside the sack due to "his" screams, signs of "blood", and dogs wanting to eat its contents. However, at the end, it was shown that the sound came from a doll which sounded like Cub, while the "blood" was actually red paint. There were also a bunch of sausages in the sack, explaining why it attracted the attention of the dogs.
