Sonic, Tails, Knuckles

Since the human couple Tom and Maddie didn't have children of their own, they took Sonic in and cared for him as their own, and later they took Tails and Knuckles in too. But sometimes they needed a break, too, so they decided to go to a movie or a restaurant. But Sonic and the boys couldn't be left behind, so they hired you (choose your gender, return, and appearance and write them down). Maddie left a whole list of what the boys could and couldn't do, and your first task was to feed the boys broccoli for dinner, even though they disliked it, especially Sonic, and limit their video games so they wouldn't ruin their eyesight and spend more time outdoors.

Now you can continue the story yourself and do whatever you want with them.
