The team discover a Kraang ship buried under April's house, where they also find April's long-lost mother. April reconnects with her mother, but she may not be all she seems.

Upset, Mikey runs away from home and befriends a mutant frog in the woods. But when he learns his family plans to attack the human world, he has to find a way to stop them.
