Monster Blood IV by R.L. Stine

2.5

 I'm honestly pretty over the Monster Blood series. It's the same kids having the same problems, only the problems are SLIGHTLY different. This time the Monster Blood is blue and does something completely different than the green Monster Blood. Still, it's a can of the stuff and the kids STILL haven't learned their lesson after the last three books. I choked this one down. The different types of Monster Blood is a fascinating premise, but I just can't get over the fact the same exact thing keeps happening to these kids because the kids don't learn. It also dragged out too much for more with its over-the-top twists just to pad the story and make the ending drag.

My recommendation is choosing only one of the four Monster Blood books to read, which ever one sounds the most interesting. Leave the others alone.
