It was nice to see a different part of story on your stream. You can actually get the rat father. But you have to get him before his son. The son also starts to get angry when his father is gone and punch really bad. Then you get spirit of the second son plus you are the one calling the big rat prince by throwing part of his father down there 😊
you can zoom in to the drawing for more backgroubd story of that chapter. the more bosses including the hidden one you defeated, the more story telling.
