In season 4, despite the Nexo Knights' victory in the previous episode, the entire kingdom is in depression. Lance gains the idea to throw a party in honour of Clay saving Queen Halbert in order to lighten everyone's moods. However, Clay's petrified body is painted and placed in his remote-controlled battle suit in order to avoid suspicion. Meanwhile, Robin and Ava have to deal with Sir Bricklyn and his colleague Sir Grimace when they take some students from the Knighton Academy on a tour of the Fortrex (and constantly prank them) for the school field trip.
