Movie tie-in merchandise!
This is the 13 inch plush doll. Talking plush and figures for Sonic have been done before, so something like this was sure to be on the merch menu.
The box says "Brings the movie to life with 10 sounds" You get 7 phrases when you squeeze him, but also 3 different sound effects when you shake him. So, that's 2 kinds of interactivity, which is nice/more quality going on. He comes in a 'chair box' with open front, as seems traditional/common to plush in the 2000s or so. But what's unique is...he's standing! Usually absolutely every character is always sitting in these.

The Nike shoes cash grab has been erased from the sneakers.
The fabric isn't fuzzy or soft, it is instead printed/smooth, so it can have the 'hairy cg texture' of the movie critter-Sonic. The ears are kind of...oddly crumpled? These are factory photos & they left them like that...but then look at the art on the box, that photo & also the movie CG isn't crumpled.
Also notice how they changed the doll's proportions to more closely resemble actual-Sonic, the body is MUCH smaller and follows modern-Sonic shape rather than the shape you see on the book cover above & even on the side of the box. It seems likely this will turn up in Target when it releases along side the actual movie in Feb.

Opinion Zone:
YES they're doing everything they can to minimize 'movie-ness' about the merchandise so it'll actually sell. Big-bean-body up there isn't attractively designed to the consumer-eye, so they're trying to push as much toward 'actual normal modern Sonic' as they can at every trun with this stuff. There's a reason Sonic classic/modern design is so damm iconic! You're not going to 'fix' him by winding him up in sports tape and giving ragged quills, or making him into a funky blue monkey. What's rotten is all these things proving their own point along-side the internet flame-out edit / redo.
Opinion 2: The standing up doll in the box is actually a really good way to pose something. Good idea.
