I thought this was good, but not great. I guess I'm not into this series that much. I think it was a little too long. It's still quite nice to see these characters again. It is nice to see how cute it all is. It still has stuff about poison, but is not all that dark.
I can appreciate that approach. You know how to create a pretty interesting setup. I don't know why they're eating batteries. For people, that's already poison. Hopefully, they're hurt by salt like slugs and snails.
