What is the connection between eTrade and the cartoon girl?

It's hard to say. Maybe it's a creative combination in an artistic work or a unique concept in a story.

It could be that the girl is driving the car or maybe the car belongs to the girl. It's all about their interaction.

Maybe the girl is friends with the gargoyles or has some adventure related to them.

Perhaps Arthur and the cartoon girl are rivals or have a relationship that drives the plot forward. Without more details, it's hard to say exactly how they're connected.

Perhaps the girl's imagination brings the cartoon train to life and they have all kinds of fun together.

I'm not sure. Maybe they are friends or have some sort of interaction in the story.

It could be a creative story element where the girl loves tacos and has adventures related to them in the cartoon world.

Maybe the girl cartoon character has maracas as her favorite musical instrument and uses them to express her emotions or solve problems in the cartoon.

The connection could be that the girl is a fan of mimeograph cartoons and has a collection of them. Or it could be that the girl is featured in a mimeograph cartoon as the main character.

Well, it could be that the girl discovers the chameleon in a magical cartoon forest and they become friends. Or perhaps the chameleon has some special power that helps the girl in her adventures.
