1

Hakuoro is working and finds that he is hungry so he sets out to find Eruruu, but is unable to locate her. Upon going to the food storage hut, Oboro approaches him and helps him find some food hidden in a secret compartment. Eruruu almost catches them and frustratingly remarks how the hidden food was spoiled and leaves. Afterwards, Hakuoro and Oboro are stricken by serious stomach problems and fight to go to the restroom before the other does. However, the situation is further complicated by Aruruu, who has shown up ready to dive headfirst into Hakuoro. (Source: Wikipedia)
