This is the "Let's Go Sonic" PJ set at Target.
How many pajamas is Target going to let out with Sonic? Apparently 'lots', because fall 2021 gets yet another pajama in the boys/kids area. It is modern themed, with various poses for Sonic (fairly large) scattered all over a mottled blue background with rings. There is a slogan here on it, which you can see part of (to the left) in red; "Let's Go" (Let's go...to bed...maybe)
Oddly, this is another 'hoodie pj', and the hood is a wacky 'costume style' where it's a Sonic face on the hood. There is a zipper for the neck, and the sleeves are probably about 3/4, while it is a long-pants set.
Do people actually ever use the hood on hoodie pjs? If you sleep in it, the hood can twist around your neck like a scarf and be annoying, or ball up behind your back as you lay down and then be annoying. There's no way to zip it off, either. Hoods for outdoor wear make a lot of sense, but going under the covers in one hmmm.
