Im pretty sure they would take a closer look at him to ake sure hes not one of eggman's robots. And then they would take him in and take care of him I guess?
make sure he's not on the evil side {Not Shadow though because he wouldn't really care since he wouldn't help anyone other than Maria} They would take care of Timmy I guess. They would probably learn about his 요정 anyways since they can run in quick without his 요정 even having a chance to disappear in the fishbowl anyways they still would be putting him in danger since they're always attacked.
