They vary in size but are much larger than regular mealworms. We first found them floating and seeing in the water in the basement of the Ellis house.
After interrupting the ceremony of the cult there was wooden cigar box which Percival opened and as he was trying to close it after seeing the two worms, he heard “too should eat me” Percival tried to resist the suggestion but it was to strong and he ate one of the worms.
Afterwards Percival felt invigorated and healthier, though at the same time entropy and decay were all the his mind could focus upon and the death around him no longer bothered him.
