When does Wander Over Yonder return?

Wander Over Yonder is an American animated television series that aired on Disney Channel and Disney XD. The series follows Wander, a nomadic, helpful, and overly-optimistic intergalactic traveller and his best friend and steed, Sylvia the Zbornak, as they travel from planet to planet helping people to have fun, play, and live free. The show's first season is episodic; there are very few strong ties between episodes, and they can be viewed independently of each other. In the second season, a more sequential story is introduced; as Lord Dominator begins to conquer the galaxy, the show's tone becomes more serious.
