We're approaching the last of our Totoro figures, and this is one of those that don't stand on their own very well.
So we have two Totoros trying to balance on an upside-down mushroom with a dust sprite to boot. Given the lack of stability of the figure, I think that explains why they look so terrified.
To be fair, their experiences seem to change slightly depending on what angle you look at them from. In this case, that Chibi Totoro looks funnier than before. Or maybe it's just me.
