I sincerely apologize for the crap level of this translation. Please disregard when someone competent translates this:
The Marisa and its children have been searching for water. Dehydration is a death of a thousand cuts. After 10 minutes of searching, the marisa found a potential easy place to hide from the sun. one of the Ko's lets out an "its an easy place", and the marisa chides it for making a home declaration. (the implication being that this marisa is a gutter yukkuri but isn't completely trash) The marisa wants to investigate, but notices a strange smell of children who have already turned to an unbelievable slight. If marisa doesn't notice that the smell is mold and death, she and the ko's will join the other family in a slow, painful death.
