The Pirate Explorer's profile in the logbook says his favorite video game is Ice Climbers, which is clearly referencing Ice Climber on the NES. This is likely because Ice Climber takes place on a snowy mountain, where Pirate Explorers normally appear.

Zambot's profile in the log book states that it hates the stereotype that all zombies know "Thriller". This is a reference to the Michael Jackson song "Thriller", whose music video is known for having zombies in it.
