I just put this into YouTube search and got results that contraindicate your claim¹:

> "sanic" the hedgehog

The quotes seem to shut down autocorrect

1: there's nothing that I see about the T-shirt, but the first result is titled "Sanic DA hedgeh0g". I will not be looking at what this video is. Several other results also include the word "sanic" in relation to the hedgehog.
