Complete Monster: Andrew Toggle runs the piano school where Jerry Hawkins's parents send him. While he appears to be a friendly, eccentric caretaker who shows Jerry around the school, it soon becomes clear who he really is. Creating Dr. Shreek to act as a figurehead, Toggle would lure people of all ages to his school for lessons, only to murder them and make their hands into piano-playing automatons. One victim's ghost was condemned to haunt Jerry's house to warn him away, and it's implied at one point that he could hear another crying for help. When the boy finally discovers his crimes, Toggle calmly explains that he did it partially to further his robotics research and also because he thinks music sounds so much better without human mistakes. And when he's reprimanded by the ghost of his former music teacher, he whines like a little boy, saying he practiced every day but it was never good enough for her.
Harsher in Hindsight: Mr. Toggle's behavior towards Jerry comes off as disturbingly similar to a pedophile. Fast forward to the new 2010's and what was once harmless to read has become cringe-worthy due to the rise in pedophiles/groomers in the 21st century.
Hilarious in Hindsight: Believe it or not, a wide consistency of Dr. Toggle's inventions have actually been successfully made in real life. Let's see which inventions of his have so far come true. A robot vacuum cleaner that sweeps floor floors? We have the iRobot to thank for that. A special saxophone that is controlled by fingering and compressed air? Such device has been proven. A keyboard playing that is completely eye-controlled? You bet it exists now.
