The giantess is the central figure in the 'bad day giantess story'. There could be a wizard or a magical creature that tries to cheer her up. There may also be some merchants who usually trade with the giantess but on this bad day, they are hesitant to do so. The characters in this story would interact with the giantess based on her mood, creating different plotlines and sub - stories.
The 'bad day giantess story' could be centered around the giantess experiencing some sort of disappointment. Maybe she was expecting to meet a friend but the friend didn't show up. Her bad mood could then lead to her stomping around, causing earthquakes in the small world beneath her feet. This in turn could cause chaos for the little people who live there, and the story could be about how they deal with the giantess's bad day.
I'm not familiar with this 'bad day on the midway story', but typically in a story set in a midway, the main characters might include the carnival owner who has to deal with all the problems on that bad day. There could also be a young and adventurous visitor who experiences all the chaos and misfortunes first - hand. And of course, the workers such as the ticket - sellers and the maintenance crew who are trying to keep things running despite the difficulties.
There are often normal - sized humans in the story. They can be villagers, children, or adventurers. Their reactions to the giantess range from fear at first to acceptance and friendship as they get to know her better. For example, a young boy might be initially scared but then realize the giantess means no harm and they become friends.
In the 'giantess family story', the grandparents of the family could be main characters. They might have a lot of wisdom to pass on to the younger generation about how to live as giantesses. Also, there could be an aunt or an uncle who has some special abilities or knowledge that helps the family in times of trouble. For example, an aunt who can communicate with animals and uses this ability to protect the family's large - scale farm from pests or other threats.
I'm not sure specifically as it could vary. It might be a giantess and a regular - sized human. Maybe a male human who falls in love with the giantess.
I'm not sure exactly as the details of the story aren't given. But usually, there could be a protagonist who experiences the bad day and perhaps some antagonists who cause the trouble.
The main character is Stacey. In this story, all the events, whether it's the so - called 'big day' events or the 'giantess' - related happenings, will probably be centered around her. Her actions, decisions, and experiences will drive the plot forward.
It could be Meg. Since she's often the outcast in the show, turning her into a giantess could be an interesting twist. It would give her a new - and very literal - form of power and attention that she doesn't usually get in the show.
