In the usual cash in cash-grab...
Here comes Halloween with this accidentally scary costume. This is Movie Sonic costume, so...it's got a hairy texture printed on. It's the usual jumpsuit type thing with a hood simple costume that comes in a bag at all of the general Halloween sections & Halloween shops. It's got the movie logo, a gold ring, and is in kids sizes only. The back-photo (inset) shows that the hood is indeed spiked, but it looks like the texture for the actual back is printed on.
Do note that it doesn't come with gloves or shoes to complete the look.
