Some Sonic ideas
 

1. Sonic surrenders himself to Eggman, letting him be his (baby) slave if the mad doctor stops attempting to conquer the world.
2. After saving the Arabian Nights stories, Sonic decided to celebrate with Shahra by wishing for more than just diapers.
3. Amy Rose was an Abdl that none of her friends know about, until Rouge discovers a perfect blackmail.
4. Jet won a race against Sonic and now the Blue Blur must be the Hawk's big baby slave for a whole month.
5. Vanilla offers Blaze the chance to have a second baby/childhood since her first was harsh to the Sol Princess.
