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 start shipping slimes off to who-knows-where, the slimes left at the shop start to worry that they're next. Even as Polly tries to convince her friends that everything is fine, Boris, a grumpy green slime, starts taking things into his own hands. Then slimes start disappearing and suddenly the shop is full of zombie slimes.

With half the shop zombified and the other half scared silly, Polly has no choice but to go on a quest, along with her friends Max and Karma, to discover the truth about the slimes being shipped off and a way to save her friends before it's too late. 

Will they be able to turn everyone back into themselves? Or will the slime shop get shut down for good?
