Welcome to the Wicked Wax Museum

I read through probably seven to ten different endings before getting bored of the repetitive nature of backtracking to try other options, and I think that's a decent count for an adult reading middlegrade horror. I do remember Goosebumps books being really good in the eyes of my younger self, but this one was far better than I expected it would be in the retrospective view of an adult. In fact, it's basically a somewhat toned-down version of the movie House of Wax, albeit written before the movie existed.

Oddly, I remembered the silly puns and campy horror more than anything truly terrifying in these books, which is what made this one such a pleasant surprise. It has far more ‘gore' (mentions of a skin-scraping chamber; kids being skinned alive then coated in wax to become living wax dummies) than I'd have expected, and the silly puns and ‘bad' endings are actually amusing.

I always remember thinking that it was silly how upset some teachers got about my love for Goosebumps books when I was a kid, but then I was a kid who'd literally grown up on The X-Files so my spookiness threshold far surpassed that of most other kids in my class. Now? I might understand a little better. But also, let young horror fans live a little.

This is one of the Give Yourself Goosebumps books, and I think the series was serviced really well as a choose your own adventure. It made it both scarier and more climactic flipping back and forth through the pages. At one point I had all five fingers of one hand between pages so that I wouldn't miss any of the endings. 
I went into this hoping for a Goosebumps version of The House of Wax and to a certain extent, it is, but it also does it's own thing. A bit more supernatural, and it pulls a few characters from the original series to appear as wax figures! 
Personally a 5/5*, really enjoyed this format.
