I'm sorry but Lost in Oz
actually has one season split into two parts. You can see so in the following screenshots:
A similar decision was recently made regarding Kung Fu Panda: The Paws of Destiny
, another Amazon series where two parts of Season 1 were also named "Season 101" and "Season 102". See this thread
I will therefore be moving all thirteen episodes from Season 2 to Season 1
for Season 1, Part 2
, published by Prime Video Kids, further reinforces my stance.
