After Bip frees them, Dawn and Terry confront the Grump on the castle's rooftop, using the key to eliminate happiness. Dawn manages to subdue the Grumpies while Terry subdues the Grump but also damages the key. Dawn implores Terry to leave on the blimp, but he decides to stay with her. Through their faith, they restore the key, which undoes the Grump's magic on Groovingham. The Grump retreats to his blimp and fights with Terry while heading to Earth.
