Sonic the Hedgehog long sleeved top and sweatpants

Items did not originally go together but my son wore them together. Shirt is size Small. Pants size 7/8. Went together nicely as an outfit. While photographing, I noticed a nickel sized spot in the middle of the back of the shirt. I hadn’t noticed it before. See pic of back of shirt and one zoomed in for reference. Other than that, I did not notice any stains, rips or tears. However, these are used children’s clothes so it’s possible I may have missed something. Therefore, sold as is.
