Headscratchers / Day of the Barney Trilogy

• Where the hell BJ (Baby Bop's yellow dinosaur brother) is?
  • The fic was originally written long before BJ came along.
  • Many other stories written by the author have BJ in there, but they're not canon to the original story. He and Baby Bop were also referenced in "Son of Barney", despite the former not appearing in the original trilogy.
• Also, what's up with the pink frosting around corpses' mouths? Is it just Purple Prose for blood?
  • That would be the birthday cake, the last thing they got to eat.
