The Boohbahs are surely the main characters. They are the ones that the stories are likely centered around. In the context of 'the big bed and other stories', they would be the ones having experiences around the bed and in other situations described in the book.
Most likely, the main characters are the Boohbahs. They are probably cute and unique characters that engage in various activities. They could be little magical or very imaginative beings. Their actions and interactions, whether around the big bed or in other scenarios, form the core of the stories in this book.
I'm not sure exactly what all the stories are in it. But I assume there could be stories about the Boohbah characters and their adventures around the big bed and other related settings.
It could be a story about an old lady who owns the big bed. She might be the main character and there could be other characters like her cat that always curls up at the foot of the big bed. There could also be neighbors who come to visit her and sit on the big bed to chat.
I'm not sure specifically as I haven't read it in detail, but usually in such collections there are likely to be some tough - guy characters involved in the 'knockover' situations, like thieves or con - men.
As I haven't read it, I can't say for sure about the characters. But perhaps the 'little horn' is a unique character with its own personality traits.
Since I don't know the exact content of 'boohbah the little horn and other stories', I can only make some general assumptions. It could be a collection aimed at children, given the rather whimsical - sounding name. The 'little horn' might be some sort of magical or special element in the stories. The other stories might be included to offer a diverse set of reading experiences, perhaps with different settings and moods to keep the readers engaged.
I'm not sure specifically without reading it, but they could be ordinary people like a child who plays in the big front yard, a neighbor, or a family member. Maybe there's an old man who has lived in the neighborhood for a long time and has many stories to tell.
I don't know as I haven't read the book. Maybe the members of the Big Dipper Club are the main characters.
Thomas is likely one of the main characters. Others could be his friends, family, or people he interacts with during his big day.
There are also various supporting characters that add to the wackiness. For instance, there might be a character like the 'Mister Poopybutthole' - like figure who pops up randomly and says or does really odd things. These characters, along with Tim and Eric, create a really unique and zany cast for the Bed Time Stories.
Big Blonde is surely a notable character. She is likely the central figure in at least some of the stories, and her experiences are probably what drive the plot in those cases.
