So the father and spawn went on a picnic in a forest park with whatever lunch in the plastic bag. To a yukkuri those dirty and weird food are a feast. maricha saw what a pet maricha eats is completely different from what she eats so it didn't taste as good as before. Then they heard pet maricha is getting a eclare for dessert, although they have no idea eclare is it must be good so father plans on destroying the human so maricha can get the dessert. The human takes out a desist spray and it causes them to leak weird liquid and dropped the plastic bag lunch. The human was surprised at how badly they react to the spray and how dirty their lunch is. She takes her pet yukkuri elsewhere.
Here maricha is saying how her easy lunch is raw trash to human and mister <foods> are not meals but trash. The father takes it all into her hat and crawls away (not bounce away).
This is just before being put inside of marisa's hat.
To clarify, those dirty and weird food are the same as what the pet is eating, minus the weird colour, smell, and liquid. Marisa pops out of the bush surprising the miss and her pet. Since the pet is getting the delicious food then the eclare must be given to the little spawn. The miss hid her pet before spraying so likely the spray has large radius or she's being considerate of her pet.
