The Time Stones are two red jewels embedded as eyes in a brown owl-shaped mask with a small dark beak which can be split down the middle. Each half of these mask parts have a handle on the side that can be hold onto.
Powers and abilities
When when the Time Stones' two masks are joined together, the Time Stones allow their wielders to travel through time and space. When two wielders are using the Time Stones at the same time, they must synchronize their thoughts by concentrating hard on the same time and location they want to go. If one wielder lets their thoughts wander however during the process however, it will result in a mislocation in time.
For an unprecedented time, the Time Stones have resided in the Floating Island's temple. Only by defeating the temple guards, entering the temple, and answering the riddle of the Keeper of the Time Stones may one receive the Time Stones. However, many on Mobius believed these relics to be only a myth.
The first known people to reach the Time Stones were Sonic and Princess Sally, after Sally answered the Keeper of the Time Stones' riddle (which was "Time"). Receiving the Time Stones from the keeper and his instructions on how to use them, the pair planned to use them to go back to Mobotropolis a week before Robotnik's takeover of Mobotropolis in an attempt to stop Robotnik's uprising from happening. This attempt ultimately failed as Sonic began thinking about chili dogs instead of the the exact date and place, causing them to arrive in the right place, but on the day of Robotnik's takeover instead. After they escaped from Robotropolis and saved the past Knothole Freedom Fighters from roboticization, Sonic and Sally used the Time Stones to go home. However, Sally was able to get the original Roboticizer plans and save her nanny Rosie from being roboticized in the future.
