Anonymous trying not to get too invested in this, but it's worth mentioning that in adventure time there are episodes that focus entirely on "girly" issues in an age-appropriate way... like an episode in which finn tries to ask pbg to a movie night, goes with marceline, and then realizes the point of the movie night is to kiss and becomes disgusted because he just wanted to watch a movie with a friend, he doesn't really think about dating yet! with gender switched the episode remains p much the same...
Another valid point brought up by somebody who watches more Adventure Time than I do.
