Time Loop is a Regular Show short. It aired on December 19, 2016.
The gang gets stuck in a time loop.
After Mordecai and Rigby get back from a gas planet, they talk about how they've never been to one and how Mordecai has read about them somewhere. Then they begin to notice how everything seems to be happening in a loop. After the third time loop, everyone begins to notice something is wrong, and Benson questions everyone to see if they did anything wrong or took an object that wasn't theirs. After which Rigby reveals he has this orb he stole from somewhere.
Eileen figures out that the orb is causing the time loops, and everyone tries to destroy it. Ways of destroying it include smashing it with a chair, Muscle Man farting on it, Rigby using his whip on it, Skips using a jackhammer on it, and a wrecking ball, all of which fail. Then after all the failed attempts, everyone just gives up and begins running away from it. However, the orb grows in size and chases after them. Then it's revealed that the dome itself is now trapped in a time loop and keeps repeating its movement.
