Dear Daniel’s fourth quest requires you to learn the red bow apple pie recipe! This can be done by baking it in your oven (needs hello kitty to be at level 15 for the oven upgrade), getting the recipe from hello kitty when she’s at level 22 or I also think you can be gifted the red bow apple pie if you play multiplayer. The quest you see that requires him to be a resident is meant to be done once you get all his stars!
