Wacky-onesie?
Here's a silly pajama with a hood. This all-in-one pj is like a costume as it has a hood to put partially over your face/head with Sonic's face on there like some of those hats. The zipper in the front is how you climb in, and it has long sleeves & long pants. They made the cuffs red (no attached 'feeties') for the legs, but too bad the sleeve cuffs aren't white to represent the gloves.
Look at the image of the back...the hood has a little ruffle of tiny stuffed spikes only on one side. This looks a little strange...but it was probably meant to sleep in/couldn't have big spikes or it would interfere. Still, sleeping in a hood might not be comfortable either way. This is at Target in winter 2019. Maybe it could also be used at Halloween? Either way, this is a funny item.
