Welcome to the Wicked Wax Musuem is the 12th book in the Give Yourself Goosebumps series.
Plot[]
A history class is taking a trip to the Wicked Wax Museum the day before it opens. You and your friends, Jake and Liz, misbehave while on the bus. Then you are told by Mr. Dunning, the teacher, that you are not allowed inside. Eventually, Jake decides to go inside and soon starts screaming, providing you with the first choice in the book: whether to go in after him or to go find help. If you and Liz go after Jake, you find out the museum's secret of making their exhibits. Unfortunately, you and your friends may end up as the newest editions. If you go for help, the two of you will run into a mysterious man named Axel. He leads you to Sybil Wicked, since he's apparently working for her, and she is looking for a new face to replace her disfigured one, and she might get yours!
