Ep 23. Teacher's Pet

In this episode of Goosebumps, entitled "Teacher's Pet," we meet a boy named Skipper. He's struggling in school, but everything changes when a new substitute teacher arrives: a strange, but captivating woman named Mrs. Maaargh. Mrs. Maaargh is different from any other teacher Skipper has ever had. She's kind, supportive, and even allows her students to call her by her first name. Skipper finds himself drawn to her, and his grades start to improve dramatically.

However, as he spends more time with Mrs. Maaargh, strange things start to happen. The other students in the class begin to change - they become more obedient, more like pets than people. Their personalities fade away, and Skipper finds himself becoming more and more like Mrs. Maaargh's favorite student - a boy named Wilson who always wears a collar.

Skipper begins to suspect that something sinister is going on. His suspicions are confirmed when he sees Wilson, wearing his collar, transformed into a literal dog. Mrs. Maaargh, it turns out, is not a teacher at all - she's an alien who has come to Earth to study human behavior. And now, she's using her powers to turn her students into pets.

Skipper realizes that he needs to escape before he, too, becomes a pet. He hatches a plan with his best friend, Wilson (who is a dog for most of the episode), to escape from the classroom and find the evidence they need to expose Mrs. Maaargh's true identity. But things don't go according to plan, and Skipper finds himself trapped in Mrs. Maaargh's lair, face-to-face with the alien herself.

In the final showdown, Skipper must use his wits and his courage to outsmart Mrs. Maaargh and save himself and his classmates from becoming pets forever. But in the end, even he may not be able to resist the allure of Mrs. Maaargh's control.

"Teacher's Pet" is a thrilling and suspenseful episode of Goosebumps that will keep viewers on the edge of their seats until the very end. With a memorable villain and an exciting plot, it's sure to be a favorite among fans of the series.
