Slime Shop by Karina Garcia

From YouTube's Queen of Slime, Karina Garcia, the first fictional story for her millions of followers!

Bailey, Sophia, and Jayden run the BSJ Slime Shop, but what the three slime makers don't know is that when they're not around, the slimes come to life!
   When the creators begin shipping slimes off to who knows where, the slimes left at the shop worry that they're next. Even as the popular slime Polly tries to convince her friends that everything is fine, Boris, a grumpy, green slime, starts taking things into his own hands. Slimes begin disappearing and suddenly the shop is full of zombie slimes.
   Can Polly and her friends Max and Karma discover the truth about the slimes being shipped off and find a way to save their friends before it's too late? Or will the slime shop get shut down for good?
