The Rangers take part in a community effort to plant trees in Angel Grove, hoping to make the city a cleaner and greener place. Rita’s forces have an entirely different idea when Squatt secretly plants an evil seed that begins growing into the monstrous Octoplant. What starts as an environmental activity quickly becomes another battle against Rita’s magic. The Rangers must protect the park and the people around it while dealing with a creature whose growth threatens to turn their peaceful tree planting project into another dangerous confrontation.
