Trivia

 * Fred doesn't say "I knew I should've stayed home today" in this episode.
 * This is one of the episodes where Fred wasn't nervous about the field trip.
 * Fiona's last name is revealed to be Kent.
 * Clyde is seen without his cap during one of the underwater scenes.
 * Instead of the producer, Gerri Poveri appears in the Phone Segment answering the phone.
 * The first time The Magical School Bus sinks underwater with the weights attached to it, it started moving through the water like an actual submarine. The second time it sinks when crumpled up to a small size, it keeps on sinking till it hits the bottom. Perhaps the propeller couldn't turn when The Magical School Bus was crumpled because it was too crumpled up for the propeller to turn.
 * To crumple the bus, Bonnie & Clyde activated four crumple control buttons to crumple up The Magical School Bus to cause it to sink. To uncrumple it, the kids pulled hard on each side of The Magical School Bus, while Blossom and Peep pushed hard on the inside of it. Perhaps they couldn't use the crumple control buttons to uncrumple The Magical School Bus like they used them to crumple it because they were still jammed (as Blossom said when they were rising back up to the surface when Fiona left them).
 * Maddie's voice sounded like a teenager in the first 2 lines she spoke in this episode. The reason for this is because Stephanie Sandra was going through puberty at the time.
 * This is the last episode of the series to air 2 years before another. The next episode was In a Beehive.
