Alex Manalo and his dad have just moved back to Sacramento to help out with their extended family's struggling Filipino market. While Alex likes helping in the store, his true passion is making slime! He comes up with his own recipes and plays with ingredients, colors, and different bumpy or sparkly bits, which make his slime truly special. A new friend encourages Alex to sell his creations at school, which leads to a sell-off battle with a girl who previously had a slime-opoly. Winner gets bragging rights and the right to be the only slime game in town.

But Alex's dad thinks Alex should be focused more on traditional boy pastimes and less on slime. As the new soccer coach, Dad gets Alex to join the team. Even though he hates sports, Alex gives in.

Alex is battling on multiple fronts--with his new friends at school, and with his dad at home. It will be a sticky race to the finish to see who oozes out on top.
