Halloween // Family idea

I have two girls. one will be 2 1/2 years old and one will be 7 months for Halloween. I was trying to think of cute ideas. however i asked my multiple ways if she could dress up as anything what would she want to be. or what does she want to dress up as. every time she has answered “a bean”

I am not sure how to make a bean costume or how to incorporate it in to a family costume.

I have an old skunk costume she wore as a baby so I was hoping to do like a woodland family. or even Anything else I would be ok with.
I don’t want to ignore her request because she gives the same answer everytime but really I’m not creative or crafty so I’m not sure how I’ll pull this off
