Gets a Bright Idea is a Magic School Bus TV tie-in book that's based on the episode of the same name.
Plot[]
Strange things start happening to Ms. Frizzle's class when they go to see a Light Show. Right after the show, Arnold and his cousin Janet disappear! Then all the lights in the theater go out. Could the theater be haunted by ghosts, like Janet said? The next thing the kids see is a spooky image above the stage and it looks like the ghost of Arnold! Keesha is sure it's all a trick, but how is it done? Luckily, the Friz arrives with the Magic School Bus to help sheds some light on this mystery.
Differences from TV Show[]
- It is mention in the book that Dorothy Ann and Tim land on the side of the stage, but doesn't show nor exclaim that they go under the stage (as they do in the TV show).
- The part with Arnold's glasses appearing as a ghost is cut.
- The part where Carlos grabs Arnold away from Janet is shown in the theater rafters (instead of on the audience floor).
