Medieval Castle is the second book in Ms. Frizzle's Adventures, a part of the 1986–2021 “classic” book series. It follows the adventures of Professor Frizzle and a select few of her students. Only one student accompanies her this time, that being Arnold.
Plot[]
"Ms. Frizzle travels back in time to a medieval castle -- and teaches readers all about the Middle Ages. With her reluctant student, Arnold, the Friz slips through a mysterious trap door -- and they end up in the Middle Ages! There, they explore a medieval castle, meeting the people who live there and learning about everyday life within the castle walls. When the castle is threatened by invaders, Arnold and the Friz don chain mail to lead the defense. They repel the invaders just in the nick of time, then they joust and feast before returning to the 21st century. With their careful research and trademark wit, Cole and Degen introduce the many facets of medieval life."
Trivia[]
- This mentions that Arnold's middle name is Matthew.
- His surname, Perlstein, is mentioned in the episodes Going Batty, Rocks and Rolls, Goes Cellular, Frizzle of the Future, and Monster Power.
- This is the second time a character other than Dorothy Ann or Amanda Jane has his/her/their middle name revealed. The first was the CD-ROM game, Explores the Rainforest (Professor Frizzle), the third was Frizzle of the Future (Ms. Frizzle), and the fourth was Kids in Space (Ralphie).
- In the story, only Ms. Frizzle dons chain mail and fights in the castle siege; Arnold is instead sent as a scout (disguised as a rose bush) to alert the lord of the castle that they are under sieged.
