Yes, Sonic the Hedgehog exists at Universal Studios in Orlando, Florida, but not as a dedicated attraction or character meet-and-greet. Instead, you can find Sonic-themed merchandise and food items, particularly at Universal's CityWalk. However, the main theme parks do not have a specific Sonic attraction like those found in some other locations.
I'm not positive but I think that house was on the lot of Universal Studios and it was never a real house.
