Bailey School Kids book #6 is called Frankenstein Doesn't Plant Petunias. The kids have a field trip at a museum run by Dr. Victor. Victor has a tall assistant named Frank, who speaks in grunts. The kids get lost and stumble upon Dr. Victor's secret lab. They decide that Frank must be Frankenstein.
I didn't like this book very much. It was extremely short, and Frank was noticeably absent. There wasn't much evidence to prove Frank is Frankenstein, either. He's tall, and he doesn't want to be set on fire. That's about it.
The big finale takes place in the greenhouse, when a lightning storm starts destroying everything. The kids decide to help Frank save his precious flowers. In a surprise twist (?), it turns out that Frank stole Dr. Victor's growth potion, and used it on the petunias. I'm not sure how this ties into the Frankenstein story. Is there usually growth potion in the Frankenstein movies, or am I missing something here?
