The children are placed with their aunt Josephine who is defined by her fear of everything. It's a bit of a change of pace from the first two. Josephine's fear of everything comes off a bit one-note, even among the typically clueless adults in the series.

Olaf's plot is pretty obvious from the start too.

There is a scene that stands out with a bit of gratuitous transphobia and fatphobia as well.

Despite all that the relationships between the siblings and the fun of watching them work to free themselves from their situation make up for a lot and leave this a pretty enjoyable story.
