I read this book to my daughter (5) at the weekend. Nobody warned me, so I'm warning you.
Comme Des Sardines by Patrick Morin As you can see, it's in French, but the pictures pretty much tell the story. At the time of writing, there are 0 reviews on Goodreads.

Just to let parents know that the book ends (pretty quickly) in genocide.
The lovable, main characters watch their long-lost brothers and sisters get killed in their hundreds, hauled up in a fishing net.
Then, in a kind of appendix, there is a selection of tasty sardine recipes.
What .. the ... actual ... fuck ...
"Awww. Their entire family was just murdered in front of them. Never mind. I'm sure they were delicious."
