I had an idea for Melloetta since she has Pirouette Forme she would know how to dance that can start the event of the other legends doing a sexy dance for the MC without touching him and them getting covered in cum and showing off like a badge of honor. Once meloetta is on ship the other legends would try to create their own dances with a little practice help from meloetta. Victine would judge over the competition to ensure all are following the no touch rule.
The dream for regiice, registeel and regirock could be as one where as they sleep they network together to share info so they would be in same dream at same time.
