Gerald Creeper Jr. needs a new plan to survive the holidays. Why? Because he “accidentally” spent the emeralds his parents gave him to buy gifts. Oops! But no worries. He’s sure he can make it all back by helping Sam the Slime put on a holiday show for little mobs in the neighborhood. Gerald can picture it already: he’ll perform his new song “Rapping through the Snow.” Everyone at Mob Middle School will love it!
Instead, he’s humiliated when Sam wraps him in twinkly lights and dubs him a talking Christmas tree. Gerald is ready to explode, until he meets a baby zombie with a special holiday wish. With a Santa skin, a wolf-drawn sleigh, and a potion of fire-resistance (to help him safely down the chimney, can he make her wish come true?
