The "Ringo Zone" is where Ringo zapped Garnet, Hoppy, and Hopper by using the sacred magic gem of ultimate power in the episode "Garnet's Universe". It is a vast place covered with green and blue colored rings and swirls. It's a part of Steven's imaginary story about Garnet's activities.
Ringo brings Garnet, Hoppy, and Hopper to the Ringo Zone because it is there that his powers are the strongest. Garnet was forced to fight Ringo, after she defeated him, he was trapped in the Ringo Zone, forever.
- It is similar to the abilities of certain characters of Bobobo-bo Bo-bobo, who can create their own universes where other characters are forced to play by their rules and where they are in full control.
- It may also be a reference to the Phantom Zone from the Superman comics.
