Worlds will collide this Thursday, April 2 at 5:30 p.m. ET/PT as Cartoon Network premieres the first-ever Uncle Grandpa and Steven Universe crossover episode. In “Say Uncle,” Uncle G travels to Steven’s universe to rid him of his “belly blues” and get control of his powers. With help from the Crystal Gems and Mr. Gus, the two unlikely heroes embark on a magical journey that is one to remember.
The same day, a brand-new Steven Universe mobile game called Attack the Light will launch on the App Store, Google Play and Amazon. From Cartoon Network Games and developed by Grumpyface Studios, Attack the Light is the property’s first game to feature an original story by series creator Rebecca Sugar and the Steven Universe show team. The light action RPG lets players explore, solve puzzles and engage in an innovative turn-based battle system, taking inspiration from classic games.

Stupid ideas 101
I love both, so, this looks absolutely hilarious to me.
You know something? The characters in Steven Universe have 10 fingers while the characters in Uncle Grandpa have 8. Just one of the few differences between the shows. Perhaps Uncle G. can travel to alternate universes different from Pete Browngardt’s imagined universe.
