Professor Layton and the Diabolical Box/Trivia
- Homage: Watch the scene as the trio arrives at Folsense after watching Spirited Away.
- Shout-Out: The Sword Puzzle near the end feels like a Shout-Out to the final test in Indiana Jones and the Last Crusade.
- Anton looks remarkably like a cartoonish version of Alucard from the Castlevania games. The resemblance is enhanced by the fact that most characters think he's a vampire. His English voice actor must have realized this, because his voice is also similar to Alucard's in the original version of Symphony of the Night.
