A really fun 'baby daisy and baby luigi fanfiction' could be set in a world of toys. They are toys themselves and they have to work together to escape from the clutches of an evil toy collector.

A baby Homura fanfiction could focus on how she copes with the strange world around her. For example, she might be confused by the adults' actions and try to find her own sense of order.
