Hey, did you notice the gay character? I didn’t either, until I went to see the film a second time. It turns out, that giant man in “Wandering Oaken’s Trading Post and Sauna” is probably gay. When he throws in the sauna package for Kristoff, he turns to say “Hello, family!” and BAM! there they are.
The adult in the sauna is clearly implied to be his husband. Best yet, Oaken and his partner have a family — and it’s not even a thing.
