Adventure Time: Rigby uses the time machine for something stupid (like getting a free meal or something) and ends up ripping a hole in time, causing some of the AT characters (remember, AT takes place in the future) to come to the current time, and cause chaos

Steven Universe: The guys decide to have a beach party in Beach City, only for a gem monster to attack at the party, meaning mordecai and rigby and everyone else have to team with the crystal gems to stop it.

Gumball (this one would be on a MUCH smaller scale): We find out that CJ's parents live in Elmore, and CJ and Mordecai go there to visit them (yeah, we saw CJ's dad, but not her mom). Maybe CJ can be related to Mr. Small XD
