Pikathulhu was hungry: his cultists hadn't recruited anyone new since the time that he forgot to not eat all of them.
This made him very angry.
He taunted his cultists by saying, "U-G-L-Y, you ain't got no alibi -- You ugly! You ugly! Your Mama said you ugly -- Hey!"
But hi was not ugly.
He was so handsome that every person who saw him fainted.
While this did mean that he never had trouble getting a meal, it made it hard for him to make friends, and his taunting didn't help, either.
Pikathulhu, confused by the story's sudden shift in focus, decided to contact Hi and get Hi's advice on how to go about feeding himself.
Hi suggested a vegetarian diet composed of only parsnips, turnips, radish and carrots, all of which made him break out in a rash.
