The whole group goes camping on a day off. Nyarko grills some suspicious meat on the BBQ and Mahiro won't eat it. Nyarko's friend, Atko, had sent them some chocolates, but Mahiro won't eat that, either. As they wander the forest, they find an old mansion. They attempt to explore it, but a rather unexpected surprise awaited them...
Nyarko-san was kind enough to 
get them all ready for us.
¡Oh!, fue Nyarko-san 
quien se encargó de todo.
¡Ah! Ha sido Nyarko-san la que ha comprado todo.
Quem deu um jeito de aprontar
 todos para a gente foi a Nyaruko-san!
