Who knew a science project could be valuable? When Babe and Kenzie created the mobile game "Sky Whale" for a seventh-grade project, they were just hoping for a passing grade. What they got, however, was one of the most popular games of the year, which led them to create a successful business that makes millions of dollars. Not everyone is happy with the girls, though; popular rapper Double G threatens to sue them when he finds out they have used one of his songs without his permission. To avoid any legal issues Babe and Kenzie decide to partner with the music star and hire his son, Triple G, as a gaming consultant. "Game Shakers" marks a return to Nickelodeon for Kel Mitchell (Double G), who first rose to fame in the '90s on the network's series "All That" and "Kenan & Kel."
