Shin-chan gets dumped in a nature reserve and decides the whole ecosystem is his personal kingdom to conquer. The comedy isn't trying to be smart or make a point. It's just a kid being exactly the level of stupid and perverse you've come to expect, except now he's doing it to animals, plants, and whatever else gets in his way. If you've watched Shin-chan for more than five minutes, you already know if this lands or doesn't.
