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...
Come over and get wet and 
play with me in the water!
Vem cá se molhar todinho 
na água comigo, vem!
