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 traveler and his best friend and steed, Sylvia the Zbornak. 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.
