I think they meant to make a TV series out of this, but instead put three episodes into a sequel and moved on and away from Atlantis after it didn't do well in the box office.
If these stories were part of a TV series, we might watch it. But it was a randomly pieced sequel that didn't make much sense to the story overall. I found it hard to follow. Not much else to say about it!
We took inspiration by going on our own little adventure into the woods to take some pictures of the Halloween costume we have picked out this year. The kid also dressed up as Harry Potter and a Ghostbuster for some parades in the area.
