there is a lot of content farms on youtube that are meant for children where the characters are put through multiple different kinds of situations. A character that is used a lot in them is sonic, as he's put through many different situations such as pregnancy, death, and multitudes of other things. Pomni, with the rise of popularity of digital circus, is now a character that is used in these kinds of videos.

The finger family part comes from the nursery rhyme with the same name, which many content farms who make these kinds of videos use in some of their content.
